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.

The c.224C>T (p.P75L) alteration is located in exon 1 (coding exon 1) of the SNX18 gene. This alteration results from a C to T substitution at nucleotide position 224, causing the proline (P) at amino acid position 75 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
