Genes affected

REG1A (HGNC:9951): (regenerating family member 1 alpha) This gene is a type I subclass member of the Reg gene family. The Reg gene family is a multigene family grouped into four subclasses, types I, II, III and IV, based on the primary structures of the encoded proteins. This gene encodes a protein that is secreted by the exocrine pancreas. It is associated with islet cell regeneration and diabetogenesis and may be involved in pancreatic lithogenesis. Reg family members REG1B, REGL, PAP and this gene are tandemly clustered on chromosome 2p12 and may have arisen from the same ancestral gene by gene duplication. [provided by RefSeq, Jul 2008]

Nov 14, 2024

The c.55C>G (p.Q19E) alteration is located in exon 2 (coding exon 1) of the REG1A gene. This alteration results from a C to G substitution at nucleotide position 55, causing the glutamine (Q) at amino acid position 19 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
