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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2023The c.1018G>A (p.G340S) alteration is located in exon 9 (coding exon 9) of the HPX gene. This alteration results from a G to A substitution at nucleotide position 1018, causing the glycine (G) at amino acid position 340 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
