Summaries for LRSAM1 Gene

Entrez Gene Summary for LRSAM1 Gene

  • This gene encodes a ring finger protein involved in a variety of functions, including regulation of signaling pathways and cell adhesion, mediation of self-ubiquitylation, and involvement in cargo sorting during receptor endocytosis. Mutations in this gene have been associated with Charcot-Marie-Tooth disease. Multiple transcript variants encoding different isoforms have been identified for this gene.

GeneCards Summary for LRSAM1 Gene

LRSAM1 (Leucine Rich Repeat And Sterile Alpha Motif Containing 1) is a Protein Coding gene. Diseases associated with LRSAM1 include charcot-marie-toothe disease, axonal, type 2p and autosomal dominant charcot-marie-tooth disease type 2p. Among its related pathways are Class I MHC mediated antigen processing and presentation and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include ubiquitin-protein transferase activity and hormone activity. An important paralog of this gene is LRRC30.

UniProtKB/Swiss-Prot for LRSAM1 Gene

  • E3 ubiquitin-protein ligase that mediates monoubiquitination of TSG101 at multiple sites, leading to inactivate the ability of TSG101 to sort endocytic (EGF receptors) and exocytic (HIV-1 viral proteins) cargos.

Disorders for LRSAM1 Gene

(1) OMIM Diseases for LRSAM1 Gene (610933)


  • Charcot-Marie-Tooth disease 2P (CMT2P) [MIM:614436]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. {ECO:0000269 PubMed:20865121, ECO:0000269 PubMed:22012984}. Note=The disease is caused by mutations affecting the gene represented in this entry.
