Genetic defect makes brain size small

Small head syndrome (microcephaly), a congenital disorder that leads to abnormal small brain size, has been identified by a genetic defect called WDR62 that plays a key role in the formation of neurons.

According to a study published in the journal Nature Genetics on October 3, microcephaly, with signs of recognition of narrow head and forehead size, can lead to disability, language restriction and transport functions. dynamic. This disease cannot be cured.

Abnormalities in the WDR62 gene have caused microcephaly-related disorders. The condition also comes from the habitat cause, which has a significant impact of alcohol, drugs and avian viruses on the fetus.

These studies were conducted by two groups, led by Dr. C. Geoffrey Woods of Cambridge University and Dr. Christopher Walsh of Children's Hospital Boston in Massachusetts.

With independent studies, both groups showed the WDR62 gene defects after studying the genome of families with a history of microcephaly syndrome and through experiments on human embryonic and mouse cells.
