Search For "genetic mutations"
Rare mutations may have big impact on schizophrenia pathology
Updated : 3 years, 4 months ago IST
Researchers have long searched for genetic influences in schizophrenia, a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. However, the disease's genetic mutations have been identified in only a small fraction few

Research: Growing motor neurons guided by 'love-hate relationship' with bl
Updated : 3 years, 4 months ago IST
When neurons involved in movement called motor neurons form, they must build connections that reach from the brain, brainstem, or spinal cord all the way to the head, arms, or the tips of the toes. How neurons navigate these systems and "decide" where and how to grow has largely been a myste

Study: Most 'silent' genetic mutations are harmful
Updated : 3 years, 9 months ago IST
Washington [US], June 10 (ANI): According to a study by the University of Michigan, Point mutations that alter the resulting protein sequences are called nonsynonymous mutations, while those that do not alter protein sequences are called silent or synonymous mutations.
