Mutation in human CLPX elevates levels of δ-aminolevulinate synthase and protoporphyrin IX to promote erythropoietic protoporphyria [PDF]
Loss-of-function mutations in genes for heme biosynthetic enzymes can give rise to congenital porphyrias, eight forms of which have been described. The genetic penetrance of the porphyrias is clinically variable, underscoring the role of additional ...

Erythroid-specific 5-aminolevulinate synthase (ALAS2) is the rate-limiting enzyme for heme biosynthesis in erythroid cells, and a missense mutation of the ALAS2 gene is associated with congenital sideroblastic anemia.

Myopathy, lactic acidosis and sideroblastic anemia 1 (MLASA1): A 25-year follow-up
Mitochondrial myopathy, lactic acidosis and sideroblastic anemia 1 (MLASA1) is a rare disease caused by biallelic pathogenic variants in the PUS1 gene. There are eleven MLASA1 patients reported worldwide with the majority of the patients originating from

Case report: Muscle involvement in a Chinese patient with TRNT1-related disorder
The TRNT1 gene encodes tRNA nucleotidyltransferase 1, which catalyzes the addition of cytosine-cytosine-adenosine (CCA) to the ends of cytoplasmic and mitochondrial tRNAs.
