DEC 2 gene mutation

DEC 2 gene mutation

DEC2 gene mutation refers to a rare genetic variant that primarily affects sleep patterns. This mutation allows certain individuals to function optimally on less sleep than the average population, typically around 4-6 hours per night. The mutation is in the DEC2 gene, which is involved in regulating circadian rhythms.
