Genes affected

SNX4 (HGNC:11175): (sorting nexin 4) 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 associated with the long isoform of the leptin receptor and with receptor tyrosine kinases for platelet-derived growth factor, insulin, and epidermal growth factor in cell cultures, but its function is unknown. This protein may form oligomeric complexes with family members. Two transcript variants, one protein coding and the other non-protein coding, have been found for this gene.

The c.283G>A (p.G95S) alteration is located in exon 3 (coding exon 3) of the SNX4 gene. This alteration results from a G to A substitution at nucleotide position 283, causing the glycine (G) at amino acid position 95 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
