Genes affected

SNX5 (HGNC:14969): (sorting nexin 5) 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 functions in endosomal sorting, the phosphoinositide-signaling pathway, and macropinocytosis. This gene may play a role in the tumorigenesis of papillary thyroid carcinoma. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2013]

The c.889T>A (p.Y297N) alteration is located in exon 11 (coding exon 10) of the SNX5 gene. This alteration results from a T to A substitution at nucleotide position 889, causing the tyrosine (Y) at amino acid position 297 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
