For a phenotypic description and a discussion of genetic heterogeneity of nonsyndromic cleft lip/palate (CL/P), see 119530.
In 2 Indian pedigrees with isolated, nonsyndromic cleft lip with or without cleft palate segregating as an autosomal dominant trait, Radhakrishna et al. (2006) demonstrated linkage to 13q33.1-q34, with a nonparametric linkage score of 5.57 at marker rs1830756. Haplotype analysis with informative crossovers enabled the mapping of a CL/P locus to a region of approximately 20.17 cM (7.42 Mb) between SNPs rs951095 and rs726455. The phenotype was variable, ranging from unilateral to bilateral CL/P. The authors noted that CL/P is very common in patients with trisomy involving all or part of chromosome 13 (Berge et al., 2001).
