Entrez Gene Summary for FREM1 Gene

  • This gene encodes a basement membrane protein that may play a role in craniofacial and renal development. Mutations in this gene have been associated with bifid nose with or without anorectal and renal anomalies. Alternatively spliced transcript variants encoding different isoforms have been described. PubMed ID 19940113 describes one such variant that initiates transcription within a distinct, internal exon; the resulting shorter isoform (named Toll-like/interleukin-1 receptor regulator, TILRR) is suggested to be a co-receptor of the interleukin 1 receptor family and may regulate receptor function and Toll-like receptor/interleukin 1 receptor signal transduction, contributing to the control of inflammatory response activation.

  • Bifid nose, with or without anorectal and renal anomalies (BNAR) [MIM:608980]: A disease characterized by the presence of a bifid nose usually associated with renal agenesis and anorectal malformations. A bifid nose is a congenital deformity due to failure of the paired nasal processes to fuse to a single midline organ during early gestation. {ECO:0000269 PubMed:19732862}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Manitoba oculotrichoanal syndrome (MOTA) [MIM:248450]: A rare condition defined by eyelid colobomas, cryptophthalmos, and anophthalmia/microphthalmia, an aberrant hairline, a bifid or broad nasal tip, and gastrointestinal anomalies such as omphalocele and anal stenosis. {ECO:0000269 PubMed:21507892}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Trigonocephaly 2 (TRIGNO2) [MIM:614485]: A keel-shaped deformation of the forehead, caused by premature fusion of the metopic sutures. It results in a triangular shape of the head. {ECO:0000269 PubMed:21931569}. Note=The disease is caused by mutations affecting the gene represented in this entry.
