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]

Ambry Genetics

Oct 12, 2024

The c.361A>G (p.K121E) alteration is located in exon 2 (coding exon 2) of the SNX7 gene. This alteration results from a A to G substitution at nucleotide position 361, causing the lysine (K) at amino acid position 121 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
