Genes affected

SNX17 (HGNC:14979): (sorting nexin 17) This gene encodes a member of the sorting nexin family. Members of this family contain a phox (PX) domain, which is a phosphoinositide binding domain, and are involved in intracellular trafficking. This protein does not contain a coiled coil region, like some family members, but contains a B41 domain. This protein interacts with the cytoplasmic domain of P-selectin, and may function in the intracellular trafficking of P-selectin. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2012]

The c.1303A>C (p.K435Q) alteration is located in exon 15 (coding exon 15) of the SNX17 gene. This alteration results from a A to C substitution at nucleotide position 1303, causing the lysine (K) at amino acid position 435 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
