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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 15, 2021The c.50G>C (p.R17T) alteration is located in exon 1 (coding exon 1) of the SNX22 gene. This alteration results from a G to C substitution at nucleotide position 50, causing the arginine (R) at amino acid position 17 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
