Laurence-Moon Syndrome

oPatientPlus articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use, so you may find the language more technical than the condition leaflets.

Synonyms: adipogenital-retinitis pigmentosa syndrome, LM syndrome
