Abstract

Autism Spectrum Disorders are a complicated group of disorders characterized with heterogeneous genetic etiologies. The genetic investigations for this group of disorders have expanded considerably over the past decade. In our study we designed a tired approach and studied the diagnostic yield of chromosomal microarray analysis on patients referred to the Genetic and Developmental Medicine clinic in Sultan Qaboos University in Oman for autism spectrum disorders in a highly consanguineous population. Copy number variants were seen in 27 % of our studied cohort of patients and it was strongly associated with dysmorphic features and congenital anomalies.
