Genes affected
SNX19 (HGNC:21532): (sorting nexin 19) Islet antigen-2 (IA-2) is an autoantigen in type 1 diabetes and plays a role in insulin secretion. IA-2 is found in dense-core secretory vesicles and interacts with the product of this gene, a sorting nexin. In mouse pancreatic beta-cells, the encoded protein influenced insulin secretion by stabilizing the number of dense-core secretory vesicles. [provided by RefSeq, Dec 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.2693G>T (p.R898M) alteration is located in exon 9 (coding exon 9) of the SNX19 gene. This alteration results from a G to T substitution at nucleotide position 2693, causing the arginine (R) at amino acid position 898 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
