A systematic review of associations between genetic polymorphism and dyslexia in the Indian population

There is growing interest in understanding the genetic mechanisms underlying dyslexia. Accordingly, the literature on dyslexia is replete with shreds of evidence linking genes and their genetic markers with dyslexia among different populations. Even though genetic inquiries into dyslexia in the Asian population has gained interest in recent years, very little is known about the genes and their polymorphisms associated with dyslexia in the Indian population. To this end, we provide a systematic literature review that yields a dossier of genetic research that manifests the effect of the genes and their polymorphisms associated with dyslexia susceptibility in the Indian population. We conclude that the polymorphisms of the DYX1C1 and KIAA0319 genes deserve attention in replication studies on the Indian population in order to gain insight into the genetic etiology of dyslexia.
