Review On Clinical And Molecular Genetics Of Autosomal Recessive Intellectual Disability

Abstract

Intellectual disability (ID) is a relatively common phenotype with multiple etiologies. Recent progress in the genetics of ID greatly expanded our understanding of the biological defects underlying this clinical entity. While most published cohort genetic studies on ID revealed the important contribution of de novo (germline or postzygotic) variants, we focused in this study of autosomal recessive ID (ARID), that account for most of the molecular bases in ID cases in inbred populations. We discussed the current state of ARID from a clinical, molecular and genetics standpoints.
