Genes affected

HPR (HGNC:5156): (haptoglobin-related protein) This gene encodes a haptoglobin-related protein that binds hemoglobin as efficiently as haptoglobin. Unlike haptoglobin, plasma concentration of this protein is unaffected in patients with sickle cell anemia and extensive intravascular hemolysis, suggesting a difference in binding between haptoglobin-hemoglobin and haptoglobin-related protein-hemoglobin complexes to CD163, the hemoglobin scavenger receptor. This protein may also be a clinically important predictor of recurrence of breast cancer. [provided by RefSeq, Oct 2011]

Aug 23, 2021

The c.553C>T (p.H185Y) alteration is located in exon 5 (coding exon 5) of the HPR gene. This alteration results from a C to T substitution at nucleotide position 553, causing the histidine (H) at amino acid position 185 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
