EGLN1 and pulmonary hypertension: 2009; Bigham et al. 2010; Jeong et al. 2014; Graham and Mccracken 2019). In addition to EGLN1, other genes related to lung function, oxygen use, and angiogenesis had evidence for local adaptation between low‐ and high‐altitude populations: TRPM7, RBPJ, and ENSMMUT00000040566 (Table S2). TRPM7 downregulation in a hypoxia‐induced rat model was associated with pulmonary hypertension (PAH) (Xing et al. 2019). ENSMMUT00000040566 is a MAPK6 ortholog, which interacts with EGLN3 (Rodriguez et al. 2016), and both it and RBPJ are involved in angiogenesis (Ramasamy et al. 2014).
