Zinc could treat a rare genetic disorder
Paediatric encephalopathies of genetic origin cause severe motor and intellectual disabilities from birth. One of these diseases, first identified in 2013, is caused by mutations in the GNAO1 gene. In order to understand the finer details of the resulting disturbances, scientists from the University of Geneva (UNIGE) conducted atomic, molecular and cellular analyses. They discovered that a mutation in GNAO1 leads to the replacement of one amino acid by another in protein sequence.
