Erythropoietic protoporphyria, mild variant
Gene: CLPX
Entry is based on a single report (PMID: 28874591) of a novel missense variant in CPLX gene (p.Gly298Asp) in a family with erythropoietic protoporphyria. The mutation is reported to occur in the ATPase active site of human CLPX, p.Gly298Asp, and it stated by authors that it results in pathological accumulation of the heme biosynthesis intermediate protoporphyrin IX (PPIX).Three heterozygous members of the family are reported - the proband is affected, while the two relatives have been reported to have free and zinc-PPIX accumulation in erythrocytes and associated mild photosensitivity, but are without the complete clinical symptoms of EPP.
