Genes affected

SLC25A38 (HGNC:26054): (solute carrier family 25 member 38) This gene is a member of the mitochondrial carrier family. The encoded protein is required during erythropoiesis and is important for the biosynthesis of heme. Mutations in this gene are the cause of autosomal congenital sideroblastic anemia (anemia, sideroblastic, 2, pyridoxine-refractory). A related pseudogene is found on chromosome 1.

This variant has not been reported in the literature in individuals affected with SLC25A38-related conditions. This sequence change creates a premature translational stop signal (p.Ser5*) in the SLC25A38 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC25A38 are known to be pathogenic (PMID: 19412178, 25985931). This variant is present in population databases (no rsID available, gnomAD 0.01%). For these reasons, this variant has been classified as Pathogenic. -
