Letter on ‘Downregulation of EPAS1 and EGLN1 mRNA Expression Associated With High‐Altitude Adaptive Genetic Variants in Sherpa Highlanders’
, The study by Droma et al. ( 2026 ) reports that Sherpa high-landers carry significantly lower frequencies of the wild-type alleles of two EPAS1 (rs13419896:G > A and rs4953354:A > G) and two EGLN1 (rs1435166:G > A and rs2153364:A > G) intronic variants, and that whole-blood mRNA expression of both genes is markedly r...
