Genes affected

CFAP52 (HGNC:16053): (cilia and flagella associated protein 52) WD repeat-containing proteins, such as WDR16, play crucial roles in a wide range of physiologic functions, including signal transduction, RNA processing, remodeling the cytoskeleton, regulation of vesicular traffic, and cell division (Silva et al., 2005 [PubMed 15967112]).[supplied by OMIM, Mar 2008]

This sequence change replaces methionine with valine at codon 498 of the CFAP52 protein (p.Met498Val). The methionine residue is highly conserved and there is a small physicochemical difference between methionine and valine. This variant is present in population databases (rs765338836, ExAC 0.07%). This variant has not been reported in the literature in individuals with CFAP52-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
