The annual meeting of the American College of Medical Genetics (ACMG) brings together a large proportion of basic and clinical investigators of rare genetic diseases. The organizers propose a series of workshops to be held in conjunction with ACMG meetings to consider issues related to identifying needs and opportunities for collaborative research involving rare genetic diseases (RGDs) associated with birth defects, mental retardation and developmental disabilities, and would set the stage for clinical and translational research.

Autism is a complex lifelong neurodevelopmental and behavioral disorder that manifests in infancy or early childhood. Although the causes are still unknown, the data suggest that autism and Autism Spectrum Disorders (ASDs) are likely due to genetic and environmental effects. Differences in culture, socioeconomic status, environmental exposures, access to health care and other factors may influence the expression of the underlying genetic architecture and lead to alterations in prevalence and clinical severity.
