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 Bardet-Biedl syndrome.[1, 2]

There are no treatments specific to this syndrome. Management of the features outlined above is multidisciplinary:

  • Ophthalmic support for worsening vision.
  • Endocrinology advice regarding short stature and hypogonadism. Growth hormone treatment may be useful.

  • Renal opinion.

Life expectancy is lower than that of the general population. Renal disease is a common primary or contributing cause of death.
