The identification of candidate genes using cDNA microarray and the analysis of two SNPs of the reelin gene in a South African austistic population
Autism is a pervasive developmental disorder (PDD) that's incidence is approximately 1 in 158. It is four times more prevalent in males than females and is believed to be caused by both genetic and environmental factors. Research indicates that several genes are involved in autism and it is …
