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]

The c.1032G>C (p.Q344H) alteration is located in exon 5 (coding exon 5) of the HEPACAM2 gene. This alteration results from a G to C substitution at nucleotide position 1032, causing the glutamine (Q) at amino acid position 344 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
