Abstract: Down syndrome, caused by trisomic chromosome 21, is the leading genetic cause of mental retardation. Recent studies demonstrated that dosage-dependent increases in chromosome 21 gene expression occur in trisomy 21. However, it is unclear whether the entire transcriptome is disrupted, or whether there is a more restricted increase in the expression of those genes assigned to chromosome 21. Also, the statistical significance of differentially expressed genes in human Down syndrome tissues has not been reported. We measured levels of transcripts in human fetal cerebellum and heart tissues using DNA microarrays and demonstrated a dosage-dependent increase in transcription across different tissue/cell types as a result of trisomy 21. Moreover, by having a larger sample size, combining the data from four different tissue and cell types, and using an ANOVA approach, we identified individual genes with significantly altered expression in trisomy 21, some of which showed this dysregulation in a tissue-specific manner. We validated our microarray data by over 5,600 quantitative real-time PCRs on 28 genes assigned to chromosome 21 and other chromosomes. Gene expression values from chromosome 21, but not from other chromosomes, accurately classified trisomy 21 from euploid samples. Our data also indicated functional groups that might be perturbed in trisomy 21. In Down syndrome, there is a primary transcriptional effect of disruption of chromosome 21 gene expression, without a pervasive secondary effect on the remaining transcriptome. The identification of dysregulated genes and pathways suggests molecular changes that may underlie the Down syndrome phenotypes.

Abstract: Ke yW ords human genetics, positional cloning, functional genomics, machine learning ■ Abstract The availability of complete genome sequences and the wealth of large- scale biological data sets now provide an unprecedented opportunity to elucidate the genetic basis of rare and common human diseases. Here we review some of the emerg- ing genomics technologies and data resources that can be used to infer gene function to prioritize candidate genes. We then describe some computational strategies for integrat- ing these large-scale data sets to provide more faithful descriptions of gene function, and how such approaches have recently been applied to discover genes underlying Mendelian disorders. Finally, we discuss future prospects and challenges for using integrative genomics to systematically discover not only single genes but also entire gene networks that underlie and modify human disease.

Abstract: We have used a chromatin immunoprecipitation-microarray (ChIP-array) approach to investigate the in vivo targets of heat-shock factor (Hsf) in Drosophila embryos. We show that this method identifies Hsf target sites with high fidelity and resolution. Using cDNA arrays in a genomic search for Hsf targets, we identified 141 genes with highly significant ChIP enrichment. This study firmly establishes the potential of ChIP-array for whole-genome transcription factor target mapping in vivo using intact whole organisms.

Abstract: The remarkable achievements in human genetics over the years have been due to technological advances in gene mapping and in statistical methods that relate genetic variants to disease. Nearly every Mendelian genetic disorder has now been mapped to a specific gene or set of genes, but these discoveries have been limited to high-risk, variant alleles that segregate in rare families. With a working draft of the human genome now in hand, the availability of high-throughput genotyping, a plethora of genetic markers, and the development of new analytical methods, scientists are now turning their attention to common complex disorders such as diabetes, obesity, hypertension, and Alzheimer disease. In this issue, the JCI provides readers with a series dedicated to complex genetic disorders, offering a view of genetic medicine in the 21st century.

Abstract: Background In research laboratories using DNA-microarrays, usually a number of researchers perform experiments, each generating possible sources of error. There is a need for a quick and robust method to assess data quality and sources of errors in DNA-microarray experiments. To this end, a novel and cost-effective validation scheme was devised, implemented, and employed.

Abstract: Mitochondria and plastids (including chloroplasts) have a small but vital genetic coding capacity, but what are the properties of some genes that dictate that they must remain encoded in organelles?

Abstract: Background: Progressive neurological dysfunction is a key aspect of human aging. Because of underlying differences in the aging of mice and humans, useful mouse models have been difficult to obtain and study. We have used gene-expression analysis and polymorphism screening to study molecular senescence of the retina and hippocampus in two rare inbred mouse models of accelerated neurological senescence (SAMP8 and SAMP10) that closely mimic human neurological aging, and in a related normal strain (SAMR1) and an unrelated normal strain (C57BL/6J). Results: The majority of age-related gene expression changes were strain-specific, with only a few common pathways found for normal and accelerated neurological aging. Polymorphism screening led to the identification of mutations that could have a direct impact on important disease processes, including a mutation in a fibroblast growth factor gene, Fgf1, and a mutation in and ectopic expression of the gene for the chemokine CCL19, which is involved in the inflammatory response. Conclusion: We show that combining the study of inbred mouse strains with interesting traits and gene-expression profiling can lead to the discovery of genes important for complex phenotypes. Furthermore, full-genome polymorphism detection, sequencing and gene-expression profiling of inbred mouse strains with interesting phenotypic differences may provide unique insights into the molecular genetics of late-manifesting complex diseases.

Abstract: One of the grand challenges of human genetics to systematically map by gene-association susceptibility genes for complex diseases is underway. High-throughput genotyping platforms have been developed; a comprehensive map of human genetic variation (HapMap) to guide efficient marker selection is imminent and many researchers have assembled suitable cohorts of patients. Expectations are understandably high and it is timely to review the promise and pitfalls of this strategy.

Abstract: Natural selection, which can be defined as the differential contribution of genetic variants to future generations, is the driving force of Darwinian evolution. Identifying regions of the human genome that have been targets of natural selection is an important step in clarifying human evolutionary history and understanding how genetic variation results in phenotypic diversity, it may also facilitate the search for complex disease genes. Technological advances in high-throughput DNA sequencing and single nucleotide polymorphism genotyping have enabled several genome-wide scans of natural selection to be undertaken. Here, some of the observations that are beginning to emerge from these studies will be reviewed, including evidence for geographically restricted selective pressures (ie local adaptation) and a relationship between genes subject to natural selection and human disease. In addition, the paper will highlight several important problems that need to be addressed in future genome-wide studies of natural selection.

Abstract: The sequencing of the human genome and development of high-throughput microarray technologies have enhanced the detection of copy number alterations in cancer research and the study of constitutional chromosomal abnormalities. Microarray-based comparative genomic hybridization (array CGH) has integrated molecular and traditional cytogenetics and has begun to impact the clinician’s approach to medical genetics. Clinical applications of array CGH may define new genetic syndromes, expand the phenotype of existing syndromes and characterize a genomic signature of some cancers. As array CGH becomes the initial diagnostic approach for the investigation of constitutional and acquired chromosomal abnormalities, the combination of bioinformatics, robotics and microarray technology will set the stage for a new generation of high-resolution and high-throughput tools for genetic analysis, diagnosis and gene discovery.

Abstract: Recent developments in molecular biology have markedly speeded the processes involved in determining the molecular etiology of human Mendelian disorders. Nowhere are these changes more evident than in the field that is variously termed molecular dysmorphology, human morphogenesis, or human developmental biology. In contrast to the rapid changes in molecular genetics analysis, the processes and approaches of the clinical component of molecular dysmorphology have not changed substantially, and clinical analysis is therefore becoming relatively slower than molecular discovery. If clinical discovery is to maintain its deserved position at the forefront of human genetics research, new methods must be developed to acquire, archive, and analyze these data. The limitations of current phenotyping, specifically, the limitations of the collection and archiving of clinical data in medical journal case reports and case series manuscripts are demonstrated. Several provocative approaches that have been proposed to advance the field of clinical analysis are reviewed. Lastly, a specific proposal for a system of clinical analysis and archiving of data on human pleiotropic developmental anomaly syndromes is proposed to address these limitations.

Abstract: Our study of genetic homozygosity degree includes an analysis of the presence, distribution, and individual combination of 20 selected genetically controlled morphophysiological traits in the group of patients (N = 93) with congenital hip dislocation (CDH) and in control sample consisting of schoolchildren from Belgrade (N = 200). Assuming that CDH is a genetically controlled disease, we made a hypothesis that an increased homozygosity level, as well as the changed variability among the patients, could be a population-genetic parameter for the prediction of the illness. Taking into consideration our experience, as well as the experience of numerous scientists who studied the nature of the inheritance of mono- and oligogenically controlled qualitative traits, we applied a methodology to estimate the proportion of such homozygously recessive characters (HRC-TEST). This population-genetic study did not only show statistically significant difference of the middle values of genetic homozygosity (CDH: 7.1 ± 0.2; control: 5.2 ± 0.1), but of the differences in the type of distribution too, as well as the differences in the presence of certain individual combinations of such traits. The described methodology can be used in further analyses, with hope that it can be applied as an early prognosis for decreased resistance to different diseases. The frequencies of ABO blood types in the sample of CDH patients were similar to the average value of the Serbian population, while the percentage of blood group A is slightly increased. Comparing frequencies of Rh blood groups, there is no difference between tested samples.

Abstract: The regulation of gene expression plays an important role in complex phenotypes, including disease in humans. For some genes, the genetic mechanisms influencing gene expression are well elucidated; however, it is unclear how applicable these results are to gene expression on a genome-wide level. Studies in model organisms and humans have clearly documented gene expression variation among individuals and shown that a significant proportion of this variation has a genetic basis. Recent studies combine microarray surveys of gene expression for thousands of genes with dense marker maps, and are beginning to identify regions in the human genome that have functional effects on gene expression. This paper reviews recent developments and methodologies in this field, and discusses implications and future directions of this research in the context of understanding the influence of human genomic variation on the regulation of gene expression.

Abstract: Detecting and characterizing genetic predictors of human disease susceptibility is an important goal in human genetics. New chip-based technologies are available that facilitate the measurement of thousands of DNA sequence variations across the human genome. Biologically-inspired stochastic search algorithms are expected to play an important role in the analysis of these high-dimensional datasets. We simulated datasets with up to 6000 attributes using two different genetic models and statistically compared the performance of grammatical evolution, grammatical swarm, and random search for building symbolic discriminant functions. We found no statistical difference among search algorithms within this specific domain.

Abstract: This descriptive survey was undertaken to assess integration of genetics into undergraduate didactic dietetic education. The response rate was 35% (n=82) of all directors (N=232) of accredited or approved Didactic Programs in Dietetics. Although most directors (n=58 of 82) agreed that genetics is an important component of dietetics education, they expressed concerns about already-crowded curricula and lack of time, resources, and knowledge. Thirty-eight directors indicated that they had no familiarity with the core competencies in genetics for all health professionals. Genetics is included in some way in 69 of the 82 programs that responded. Courses in which genetics was most likely to be incorporated included nutrition, physiology, microbiology, and biochemistry. Only four directors reported a required course entirely devoted to genetics. Programs were most likely to meet the knowledge competency of the role of genetic factors in maintaining health and preventing disease and least likely to address the genetic counseling process and indications for referral to specialists. Applications of genetics in dietetics will continue to grow in importance. Evidence from this study indicates that current curricula provide little to no genetics content. Nutrition faculty must become more knowledgeable about genetics before being expected to increase genetics content in entry-level dietetics curricula.

Abstract: Apart from sex linkage, we know almost nothing at present of linkage in man. Yet it is certain that every defect determined by a single factor must be located in one or other of twenty-three [sic] linkage groups. Each defect must therefore be linked in inheritance with numerous other observable traits, and with some of them is probably linked closely. The search for such linkage will certainly be lengthy, and at first, disappointing. (R.A. Fisher. Eugenics, academic and practical. Eugenics Review, 27, pp. 95–100, 1935c)

Abstract: Recent genomic studies showing abnormalities in the fibroblast growth factor system in the postmortem brains of people with major depressive disorder support previous indications of a role for growth factors in mood disorders. Similar molecular pathways, volumetric changes, and the effects of exercise on mood suggest a superficial analogy, and perhaps a deeper relationship, between muscle and brain functioning.

Abstract: A survey (N = 717) was conducted to explore African Americans (n = 267) and European Americans (n = 450) knowledge, attitudes, and behaviors associated with human genetics and the interplay of family communication on such issues. Responses indicated significant race differences on familial discussions of medical history and familial encouragement to behave in healthy ways. However, there were no race differences on family conversations about genetic or prenatal testing. In addition, results revealed that media exposure was related to families' discussions about human genetics research. The communication privacy management theory (Petronio, 2002) may provide a conceptual framework with which to posit predictors of family communication about heredity and health. Implications of these findings for future family communication about genetics are offered.
