Genes affected

SNX2 (HGNC:11173): (sorting nexin 2) This gene belongs to the sorting nexin family whose members contain the phosphoinositide-binding phox (PX) domain. The encoded protein is a component of the retromer complex which plays a role in protein sorting in the endocytic pathway. This protein may form oligomeric complexes with other family members. Alternate splicing results in multiple transcript variants of this gene. Pseudogenes associated with this gene are located on chromosomes 1 and 7. [provided by RefSeq, May 2013]

The c.1213G>A (p.G405S) alteration is located in exon 12 (coding exon 12) of the SNX2 gene. This alteration results from a G to A substitution at nucleotide position 1213, causing the glycine (G) at amino acid position 405 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
