ERBB3 and polycystic ovary syndrome: Notably, we find further sub-genome-wide significant signals in/near genes encoding two of the other three EGFR family members: rs7312770 (P=2.1 × 10−7) in/near ERBB3/HER3 is correlated (r2=0.40) with the reported PCOS signal (rs705702) at 12q13.2 and rs7218361 (P=9.6 × 10−7) is a low-frequency variant ∼200 kb downstream of ERRB2/HER2.
