Genes affected

ANXA8L1 (HGNC:23334): (annexin A8 like 1) This gene encodes a member of the annexin family of evolutionarily conserved Ca2+ and phospholipid binding proteins. The encoded protein may function as an an anticoagulant that indirectly inhibits the thromboplastin-specific complex. Overexpression of this gene has been associated with acute myelocytic leukemia. A highly similar duplicated copy of this gene is found in close proximity on the long arm of chromosome 10. [provided by RefSeq, Apr 2014]

The c.375G>T (p.K125N) alteration is located in exon 5 (coding exon 5) of the ANXA8L2 gene. This alteration results from a G to T substitution at nucleotide position 375, causing the lysine (K) at amino acid position 125 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
