The SDH-specific selection signals identified by iHS were primarily associated with height (PDHX, pyruvate dehydrogenase component X), atopic asthma (TAP2, Transporter 2), and BMI-adjusted waist-to-hip ratio (HLA-B, major histocompatibility complex; HLA-C, L3MBTL3, L3MBTL histone methyl-lysine binding protein 3 and C6orf10, testis expressed basic protein 1). Here, TAP2 is linked to atopic asthma.
