PVRL1 variants contribute to non-syndromic cleft lip and palate in multiple populations.

ABSTRACT: Poliovirus Receptor Like-1 (PVRL1) is a member of the immunoglobulin super family that acts in the initiation and maintenance of epithelial adherens junctions and is mutated in the cleft lip and palate/ectodermal dysplasia 1 syndrome (CLPED1, OMIM #225000). In addition, a common non-sense mutation in PVRL1 was discovered more often among non-syndromic sporadic clefting cases in Northern Venezuela in a previous case-control study. The present work sought to ascertain the role of PVRL1 in the sporadic forms of orofacial clefting in multiple populations. Multiple rare and common variants from all three splice isoforms were initially ascertained by sequencing 92 Iowan and 86 Filipino cases and CEPH controls. Using a family-based analysis to examine these variants, the common glycine allele of
