The UCLA-University of Utah epidemiologic survey of autism : recurrence risk estimates and genetic counseling
Edward R. Ritvo,Lynn B. Jorde,A Mason-Brothers,Betty Jo Freeman,C. Pingree,Marshall B. Jones,William M. McMahon,P B Petersen,William R. Jenson,A Mo +9 more
TL;DR: The authors recently reported an epidemiologic survey of autism in Utah that revealed that autism is 215 times more frequent among the siblings of autistic patients than in the general population.

The UCLA-University of Utah epidemiologic survey of autism: the etiologic role of rare diseases.
Edward R. Ritvo,A Mason-Brothers,Betty Jo Freeman,C. Pingree,William R. Jenson,William M. McMahon,P B Petersen,Lynn B. Jorde,A Mo,Anne M. Ritvo +9 more
TL;DR: Twelve rare diseases known to cause CNS pathology were found in 26 of 233 autistic probands identified during a recent epidemiologic survey of Utah, providing the most compelling evidence to date to support the hypothesis that different diseases producing different types of CNS pathology can play an etiologic role in autism.

TL;DR: The Wechsler Intelligence Scales, Wide Range Achievement Test, and the Shipley-Hartford Test were administered to 122 parents and 153 siblings of 62 autistic probands in Utah and do not confirm prior reports from England and the United States of a high rate of cognitive and learning problems in the siblings of autistic individuals.

J. Halmayer,Joan M. Hebert,Donna Spiker,Linda Lotspeich,William M. McMahon,P B Petersen,Peter Nicholas,C. Pingree,A. Lin,Neil Risch,Luigi Luca Cavalli-Sforza,Roland D. Ciaranello +11 more
TL;DR: A multipoint sib-pair linkage analysis between autism and 35 microsatellite markers located on the X chromosome was performed, able to exclude any moderate to strong gene effect causing autism on theX chromosome.

The UCLA-University of Utah epidemiologic survey of autism: prenatal, perinatal, and postnatal factors.
A Mason-Brothers,Edward R. Ritvo,C. Pingree,P B Petersen,William R. Jenson,William M. McMahon,Betty Jo Freeman,Lynn B. Jorde,M J Spencer,A Mo +9 more
TL;DR: The etiology of the brain pathology that characteristically disrupts normal development and produces the syndrome of autism remains obscure, but data from the epidemiologic survey suggest that the role of genetic factors needs to be explored further.
