Genes affected
HPX (HGNC:5171): (hemopexin) This gene encodes a plasma glycoprotein that binds heme with high affinity. The encoded protein is an acute phase protein that transports heme from the plasma to the liver and may be involved in protecting cells from oxidative stress. [provided by RefSeq, Apr 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2023The c.812A>G (p.H271R) alteration is located in exon 7 (coding exon 7) of the HPX gene. This alteration results from a A to G substitution at nucleotide position 812, causing the histidine (H) at amino acid position 271 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
