Laurence-Moon syndrome

Synonyms: adipogenital-retinitis pigmentosa syndrome, LM syndrome

This is a rare autosomal recessive condition.

Laurence-Moon-Biedl syndrome and Laurence-Moon-Biedl-Bardet syndrome are no longer considered valid terms, because the patients of Laurence and Moon had paraplegia, but no polydactyly or obesity, which are the main characteristics of متلازمة باردت-بيدل.¹²
