Genes affected

CFAP57 (HGNC:26485): (cilia and flagella associated protein 57) This protein encoded by this gene belongs to the WD repeat-containing family of proteins, which function in the formation of protein-protein complexes in a variety of biological pathways. This family member is thought to function in craniofacial development, possibly in the fusion of lip and palate. A missense mutation in this gene is associated with Van der Woude syndrome 2. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2011]

The c.284G>A (p.R95Q) alteration is located in exon 3 (coding exon 2) of the CFAP57 gene. This alteration results from a G to A substitution at nucleotide position 284, causing the arginine (R) at amino acid position 95 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
