Abstract:
Clefts of the lip with or without cleft palate (CL/P) are one of the most common birth defects, occurring in 1/700-1/1,000 infants born alive. The nature of the genetic contribution is still to be clarified; however, some chromosome regions and candidate genes have been proposed for this malformation. Recently, a couple of genes, PVR and PVRL2, mapping in the candidate region OFC3 on chromosome 19q13.31, have been investigated because of their homology to PVRL1, a gene previously shown to cause the Margarita Island CL/P-ectodermal dysplasia syndrome. In the present work, we investigated PVR and PVRL2 genes by family-based linkage disequilibrium analysis using a sample collected from the Italian population. In contrast to previous analyses on other populations, we could not find any statistically significant association between the markers alleles and non-syndromic clefting.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
