Genes affected

HEPACAM2 (HGNC:27364): (HEPACAM family member 2) This gene encodes a protein related to the immunoglobulin superfamily that plays a role in mitosis. Knockdown of this gene results in prometaphase arrest, abnormal nuclear morphology and apoptosis. Poly(ADP-ribosylation) of the encoded protein promotes its translocation to centrosomes, which may stimulate centrosome maturation. A chromosomal deletion including this gene may be associated with myeloid leukemia and myelodysplastic syndrome in human patients. [provided by RefSeq, Oct 2016]

Apr 25, 2023

The c.793G>T (p.A265S) alteration is located in exon 4 (coding exon 4) of the HEPACAM2 gene. This alteration results from a G to T substitution at nucleotide position 793, causing the alanine (A) at amino acid position 265 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
