Laurence-Moon syndrome (Q101716)

Laurence-Moon syndrome (LMS) is a genetic disorder characterised by progressive neurological, ophthalmologic and endocrine manifestations leading to severe handicap. LMS is sometimes referred to as Laurence-Moon-Biedl syndrome or Laurence-Moon-Bardet-Biedl syndrome. The differences between Bardet-Biedl syndrome (BBS) and LMS have not been clearly defined. The absence of obesity in LMS and the presence of polydactyly in BBS may allow the two diseases to be distinguished but the occurrence of these two manifestations in BBS is variable.
