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 -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.009041548).
• BP6: Variant 11-130880697-G-A is Benign according to our data. Variant chr11-130880697-G-A is described in ClinVar as Benign. ClinVar VariationId is 784522.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
