Laurence-Moon syndrome (LMS) is a rare inherited disorder. It is thought to be inherited as an autosomal recessive genetic trait. There is some confusion regarding the difference between Laurence-Moon syndrome and Bardet-Biedl syndrome. Some researchers believe that Bardet-Biedl Syndrome is a subdivision of Laurence-Moon Syndrome, and they refer to it as Laurence-Moon-Bardet-Biedl Syndrome.
