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]

CFAP52 links:

STX8 (HGNC:11443): (syntaxin 8) The gene is a member of the syntaxin family. The encoded protein is involved in protein trafficking from early to late endosomes via vesicle fusion and exocytosis. A related pseudogene has been identified on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Collection Method: clinical testing

The c.26C>T (p.A9V) alteration is located in exon 1 (coding exon 1) of the CFAP52 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the alanine (A) at amino acid position 9 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
