SOZEN, Mehmet A.; HECHT, Jacqueline T. e SPRITZ, Richard A.. Lack of mutations in the PVRL3 gene in North American caucasians with non-syndromic cleft lip/palate. Genet. Mol. Biol. [online]. 2008, vol.31, n.3, pp. 649-650. ISSN 1678-4685. http://dx.doi.org/10.1590/S1415-47572008000400008.
Cleft lip with or without cleft palate (CLP) is one of the most common birth defects. In about 70% of cases, CLP occurs as an isolated anomaly, denoted non-syndromic CLP (nsCLP). Genetic linkage and association studies have implicated many loci in susceptibility to nsCLP, including some members of the nectin gene family. We performed mutation screening of the PVRL3 gene that encodes nectin-3 in 73 unrelated Caucasian nsCLP patients and 105 unrelated controls from North America. We detected no sequence variants in the PVRL3 gene in either the nsCLP patients or the controls. These data suggest that PVRL3 is not an important susceptibility gene for nsCLP in the North American Caucasian population.
