Genes affected

ANXA2 (HGNC:537): (annexin A2) This gene encodes a member of the annexin family. Members of this calcium-dependent phospholipid-binding protein family play a role in the regulation of cellular growth and in signal transduction pathways. This protein functions as an autocrine factor which heightens osteoclast formation and bone resorption. This gene has three pseudogenes located on chromosomes 4, 9 and 10, respectively. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. Annexin A2 expression has been found to correlate with resistance to treatment against various cancer forms. [provided by RefSeq, Dec 2019]

The c.837G>T (p.Q279H) alteration is located in exon 11 (coding exon 11) of the ANXA2 gene. This alteration results from a G to T substitution at nucleotide position 837, causing the glutamine (Q) at amino acid position 279 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
