Genes affected
SNX16 (HGNC:14980): (sorting nexin 16) 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. The protein encoded by this gene associates with late endosome membranes as is involved in tubule formation, cholesterol transport, and transport of tetraspanin CD81. The encoded protein also inhibits cell migration and tumorigenesis. [provided by RefSeq, Jan 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.948T>A (p.N316K) alteration is located in exon 9 (coding exon 7) of the SNX16 gene. This alteration results from a T to A substitution at nucleotide position 948, causing the asparagine (N) at amino acid position 316 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
