Recombinants between VWS and both LAMB2 and DAF excluded these genes from a causal role in the etiology of VWS for the families studied in this report.
In contrast, TDT yielded a significant P value of 0.04 for D1S205, supporting involvement of vWS in NSCL/P in a complex, modifying/polygenic manner rather than as a monogenic/major disease locus.
This observation supports that IRF6 is the gene responsible for VWS across different populations and that haploinsufficiency of the gene disturbs development of the lip and palate.
IcsA* was located on lateral and polar regions of smooth LPS bacteria, and was fully functional in ABM assays (HeLa cell monolayer plaque and F-actin comet tail formation) which contrasts with the R-LPS phenotype.
Since IRF6 mutations in a significant portion of VWS patients remain undetected by conventional sequencing analysis, it may be important to search for a large deletion in those patients.
These include the identification of mutations in the interferon regulatory factor-6 (IRF6) gene as the cause of van der Woude syndrome and the poliovirus receptor related-1 (PVRL1) gene as being responsible for an autosomal recessive ectodermal dysplasia syndrome associated with clefting.

The recently characterised Asp299Gly polymorphism in the lipopolysaccharide (LPS) receptor TLR4 is associated with impaired LPS signalling and increased susceptibility to Gram negative infections.

Mutations in the gene for interferon regulatory factor 6 (IRF6) have been shown to be the cause of Van der Woude syndrome, a dominant disorder that has CL/P as a common feature.
The entire 9 exons of the IRF6 gene in two brothers of Turkish origin clinically diagnosed with Van der Woude syndrome and four healthy family members were screened for mutations using a newly established denaturing gradient gel electrophoresis (DGGE) method.
