Genome-wide association study of telomere length among South Asians identifies a second RTEL1 association signal

Leucocyte telomere length (TL) is a potential biomarker of ageing and risk for age-related disease. Leucocyte TL is heritable and shows substantial differences by race/ethnicity. Recent genome-wide association studies (GWAS) report ~10 loci harbouring SNPs associated with leucocyte TL, but these studies focus primarily on populations of European ancestry.This study aims to enhance our understanding of genetic determinants of TL across...
