10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 1 2013 (January - March) Autism is a complex neurodevelopmental disorder with a significant genetic component. The prevalence of autism has been increasing globally, though exact statistics for India are not available. Several genetic markers for autism have been studied. These include chromosomal abnormalities, copy number variations, submicroscopic cytogenetic anomalies, single nucleotide polymorphisms and other point mutations. This review gives details on the current data available on these genetic markers of autism, with a focus on single nucleotide polymorphisms. Studies on SNPs within candidate genes on each chromosome are dealt with, including some details on which populations show which variation. Methodology involved in analysis of SNPs, i.e. techniques in SNP genotyping are also reviewed, focusing on those techniques that are simple and economically feasible in the Indian scenario.
