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.989G>A (p.R330Q) alteration is located in exon 12 (coding exon 11) of the SNX5 gene. This alteration results from a G to A substitution at nucleotide position 989, causing the arginine (R) at amino acid position 330 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
