Gene ID: 3250 | Gene type: protein coding

About HPR

Cytogenetic location: 16q22.2 Genomic coordinates (GRCh38): 16:72,063,226-72,077,246 (from NCBI)

This gene has 4 transcripts (splice variants), 140 orthologues and 16 paralogues. Restricted expression toward liver (RPKM 3276.0).

Summary

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]
