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]

Ambry Genetics

May 10, 2024

The c.412T>C (p.W138R) alteration is located in exon 5 (coding exon 5) of the HPR gene. This alteration results from a T to C substitution at nucleotide position 412, causing the tryptophan (W) at amino acid position 138 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
