title: Supernumerary nipple as a cutaneous marker of mitral valve prolapse in Asian Indians.
abstract: We studied 68 Asian Indians from South India with supernumerary nipple (SN) and 49 age- and sex- matched controls without SN for evidence of mitral valve prolapse (MVP) and associated features. We found that MVP and its forme fruste were more common in the SN group (odds ratio 6.0, 95% confidence intervals 2.16 to 16.63), indicating an association of SN with MVP.
