Genes affected

SNX22 (HGNC:16315): (sorting nexin 22) The protein encoded by this gene is a sorting nexin that is found in the cytoplasm, where it interacts with membrane-bound phosphatidylinositol 3-phosphate. The encoded protein may play a role in intracellular trafficking. Two transcript variants, one protein-coding and the other not protein-coding, have been found for this gene.

The c.578C>T (p.P193L) alteration is located in exon 7 (coding exon 7) of the SNX22 gene. This alteration results from a C to T substitution at nucleotide position 578, causing the proline (P) at amino acid position 193 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
