Common gene variants for skin tone found – LIFE

A study of nearly 300 people living in different parts of India found that nine single-base variants (single-nucleotide polymorphisms or SNPs) account for 31% variation in the colour of the skin.

Researchers at the Centre for DNA Fingerprinting and Diagnostics (CDFD), Hyderabad, tested 30 SNPs that were earlier studied for skin colour in other parts of the world. Based on certain criteria, only 22 of the 30 SNPs were found suitable for statistical test in the Indian population.

The two-member team of Dr. Madhusudan Reddy Nandineni and Anujit Sarkar found that only nine SNPs have significant association with skin colour in people living in India.
