| abstractText | BACKGROUND: Genome-wide linkage analysis and whole genome sequencing in a Van der Woude syndrome (VWS) family revealed that the SNP, rs539075, within intron 2 of the cadherin 2 gene (CDH2) co-segregated with the disease phenotype. RESULTS: A study with nonsyndromic cleft lip with or without cleft palate (NSCL+/-P) cases (N=292) and controls (N=287) established association of this SNP with NSCL+/-P as a risk factor. RT-PCR based expression analysis of the SNP-harbouring region of intron 2 of CDH2 in the clefted lip and/or palate tissues of 16 patients revealed that the mutant allele expressed in all those individuals having it (hetero-/homozygous), whereas the wild type allele expressed in <50% of the samples in which it was present. The intronic transcript was also present in the prospective lip and palate region of 13.5dpc mouse embryo, detected by RNA in situ hybridization and RT-PCR. CONCLUSIONS: These results including the in silico, characterization of the ~200nt-intronic transcript showed that conformationally it fits best with noncoding small RNA, possibly a precursor of miRNA. Its function in the orofacial organogenesis remains to be elucidated which will enable us to define the role of this mutant ncRNA in the clefting of lip and palate. |
