Cleft lip and palate transmembrane 1 (IPR008429)

Short name: CLPTM1

Family relationships



Clefts of the lip and/or palate (CL/P) are some of the most common birth defects. They may be categorised into syndromic or non-syndromic types, with syndromic defects having an underlying chromosomal or teratogenic cause. Around 70% of clefts are non-syndromic and individuals have no typical physical or developmental abnormalities; these clefts generally show polygenetic behaviour and complex inheritance [PMID: 16122939]. Studies have identified regions on chromosomes 19 and 11 which may be involved in non-syndromic cleft lip and palates; this included a novel gene on chromosome 19, cleft lip and palate-associated transmembrane protein 1 (CLPTM1) [PMID: 9828125]. The Poliovirus receptor-related 1 gene (PVRL1), which is located on chromosome 11, has also been shown to associate with non-syndromic cleft lip and palates [PMID: 11559849, PMID: 19715471].

CLPTM1 encodes a transmembrane protein and has strong homology to two Caenorhabditis elegans genes, suggesting that CLPTM1 may belong to a new gene family [PMID: 9828125]. This family also contains the Homo sapiens cisplatin resistance related protein CRR9p which is associated with CDDP-induced apoptosis [PMID: 11162647].
