Autism Patients Carry Common Sequence Variations In Gene, Study

The gene playing a potential role in autism also helps in determining empathy quotient in people.


A recent study reveals that autism patients are more likely to carry specific sequence variations of a particular gene. Interestingly, the same gene is also linked to empathy quotient in the general public, the researchers claim.


The variations in the gene are possible indicators of Asperger Syndrome, an autism spectrum disorder.


The study was conducted by researchers at Autism Research Centre in Cambridge University and was led by Professor Baron-Cohen. The researchers looked for the sequence variations called single nucleotide polymorphisms or SNPs in the gene GABRB3. GABRB3 is the key gene that regulates the functioning of a neurotransmitter, gamma-aminobutyric acid, which contains a number of SNPs that vary with population. The gene GABRB3 is a potential indicator of Asperger Syndrome
