The possible relationship between Laurence-Moon-Biedl-Bardet syndrome and a schizophrenic-like psychosis.

The Laurence-Moon-Biedl-Bardet syndrome is probably transmitted hereditarily and recognizable mainly by: a) retinitis pigmentosa; b) hypogonadism and obesity; and c) orthopedic anomalities such as polidactylia, syndactylia, and acroecephalosyndactylia with oligophrenia. Sometimes, other disturbance, mainly dermatological (alopecia), neurological, urological, endocrinological, and, rarely, congenital heart defects, may coexist.
