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]

Ambry Genetics

Nov 27, 2023

The c.164T>C (p.V55A) alteration is located in exon 3 (coding exon 3) of the SNX17 gene. This alteration results from a T to C substitution at nucleotide position 164, causing the valine (V) at amino acid position 55 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
