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]

HPX (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.1099C>T (p.P367S) alteration is located in exon 9 (coding exon 9) of the HPX gene. This alteration results from a C to T substitution at nucleotide position 1099, causing the proline (P) at amino acid position 367 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
