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

Sep 29, 2023

The c.950G>A (p.R317H) alteration is located in exon 10 (coding exon 10) of the SNX17 gene. This alteration results from a G to A substitution at nucleotide position 950, causing the arginine (R) at amino acid position 317 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
