Summaries for TMCO1 Gene

Entrez Gene Summary for TMCO1 Gene

  • This locus encodes a transmembrane protein. Mutations at this locus have been associated with craniofacial dysmorphism, skeletal anomalies, and cognitive disability. Mutations at this locus have also been associated with open angle glaucoma blindness. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

GeneCards Summary for TMCO1 Gene

TMCO1 (Transmembrane And Coiled-Coil Domains 1) is a Protein Coding gene. Diseases associated with TMCO1 include Craniofacial Dysmorphism, Skeletal Anomalies, And Mental Retardation Syndrome and Sprengel Deformity.

UniProtKB/Swiss-Prot for TMCO1 Gene

  • Calcium-selective channel required to prevent calcium stores from overfilling, thereby playing a key role in calcium homeostasis (PubMed:27212239). In response to endoplasmic reticulum overloading, assembles into a homotetramer, forming a functional calcium-selective channel, regulating the calcium content in endoplasmic reticulum store (PubMed:27212239).

  • Craniofacial dysmorphism, skeletal anomalies and mental retardation syndrome (CFSMR) [MIM:213980]: A disorder characterized by craniofacial and skeletal anomalies, associated with mental retardation. Typical craniofacial dysmorphism include brachycephaly, highly arched bushy eyebrows, synophrys, long eyelashes, low-set ears, microdontism of primary teeth, and generalized gingival hyperplasia, whereas Sprengel deformity of scapula, fusion of spine, rib abnormities, pectus excavatum, and pes planus represent skeletal anomalies. {ECO:0000269 PubMed:20018682, ECO:0000269 PubMed:23320496, ECO:0000269 PubMed:24194475}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Glaucoma, primary open angle (POAG) [MIM:137760]: A complex and genetically heterogeneous ocular disorder characterized by a specific pattern of optic nerve and visual field defects. The angle of the anterior chamber of the eye is open, and usually the intraocular pressure is increased. However, glaucoma can occur at any intraocular pressure. The disease is generally asymptomatic until the late stages, by which time significant and irreversible optic nerve damage has already taken place. In some cases, POAG shows digenic inheritance involving mutations in CYP1B1 and MYOC genes. {ECO:0000269 PubMed:21532571, ECO:0000269 PubMed:22714896}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
