Genes affected

KIRREL2 (HGNC:18816): (kirre like nephrin family adhesion molecule 2) This gene encodes a type I transmembrane protein and member of the immunoglobulin superfamily of cell adhesion molecules. The encoded protein localizes to adherens junctions in pancreatic beta cells and regulates insulin secretion. Autoantibodies against the encoded protein have been detected in serum from patients with type 1 diabetes. This gene may also play a role in glomerular development and decreased expression of this gene has been observed in human glomerular diseases. This gene and the related opposite-strand gene nephrin (GeneID: 527362) are regulated by a bidirectional promoter. [provided by RefSeq, Jul 2016]

Nov 09, 2024

The c.790G>A (p.G264R) alteration is located in exon 7 (coding exon 7) of the KIRREL2 gene. This alteration results from a G to A substitution at nucleotide position 790, causing the glycine (G) at amino acid position 264 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
