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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.6984112E-6).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.911 is higher than 0.05.
