Summaries for Laurence-Moon Syndrome

NIH Rare Diseases : 49 Laurence-Moon syndrome is a rare condition that affects many different parts of the body. Signs and symptoms vary but may include cerebellar ataxia; eye abnormalities (primarily affecting the choroid and retina); peripheral neuropathy; spastic paraplegia (progressive weakness and stiffness of the legs); intellectual disability; congenital (from birth) or childhood hypopituitarism; and short stature. Laurence-Moon syndrome is caused by changes (mutations) in the PNPLA6 gene and is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person. Until recently, Laurence-Moon syndrome has been associated with Bardet-Biedl syndrome but newer research determined that they are separate conditions. Last updated: 6/18/2015

MalaCards based summary : Laurence-Moon Syndrome, also known as lnms, is related to retinitis and oliver-mcfarlane syndrome, and has symptoms including ataxia, obesity and finger syndactyly. An important gene associated with Laurence-Moon Syndrome is PNPLA6 (Patatin Like Phospholipase Domain Containing 6). The drugs alpha-MSH and Hormone Antagonists have been mentioned in the context of this disorder. Affiliated tissues include eye, pituitary and retina, and related phenotypes are Increased mitotic index and cardiovascular system

OMIM : 53 Laurence-Moon syndrome has a clinical presentation similar to that of Oliver-McFarlane syndrome (275400), including chorioretinopathy and pituitary dysfunction, but with childhood onset of ataxia, peripheral neuropathy, and spastic paraplegia and without trichomegaly. Historically, Laurence-Moon syndrome has been associated with Bardet-Biedl syndrome (see BBS, 209900) (summary by Hufnagel et al., 2015). Oliver-McFarlane syndrome is an allelic disorder. (245800)

UniProtKB/Swiss-Prot : 71 Laurence-Moon syndrome: An autosomal recessive syndrome characterized by progressive spinocerebellar degeneration, spastic paraplegia, mental retardation, hypogonadism, dwarfism, and chorioretinopathy. Trichomegaly is absent.
