Genes affected
SNX18 (HGNC:19245): (sorting nexin 18) 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, but contains a SH3 domain. Multiple transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.173T>A (p.V58E) alteration is located in exon 1 (coding exon 1) of the SNX18 gene. This alteration results from a T to A substitution at nucleotide position 173, causing the valine (V) at amino acid position 58 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
