Even though genes can influence the structure and function of brain, it might have a limited influence on mind. The genetic basis of cognitive processing have been primarily derived from observations on variations in IQ (as much as 50% variation in IQ has been attributed to genetic variation) and specific cognitive effect of genetic abnormalities in humans (e.g. dyslexia, syndromic mental retardation, autism). The prevailing hypothesis is that gene abnormalities result in structural abnormalities of the brain leading to cognitive, emotional or behavioral abnormalities . Abnormalities of neurodevelopment, particularly that of the prefrontal cortex, have been observed in antisocial groups. Similarly, abnormalities of cortical thickness, especially in the brain regions related to social behavior, have been observed in autistic children .
