Genes affected

SNX7 (HGNC:14971): (sorting nexin 7) 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, and its exact function is unknown. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 11. [provided by RefSeq, Jun 2010]

May 23, 2024

The c.195G>A (p.M65I) alteration is located in exon 2 (coding exon 2) of the SNX7 gene. This alteration results from a G to A substitution at nucleotide position 195, causing the methionine (M) at amino acid position 65 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
