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.

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Sep 21, 2018	The R117X variant in the SLC25A38 gene has been reported previously in both the homozygous state, and the heterozygous state in the presence of a second SLC25A38 variant, in association with sideroblastic anemia (Guernsey et al., 2009). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. This variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). We interpret R117X as a pathogenic variant. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 28, 2022	This sequence change creates a premature translational stop signal (p.Arg117*) 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 (rs121918330, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with sideroblastic anemia (PMID: 19412178, 21393332, 32605921). ClinVar contains an entry for this variant (Variation ID: 1118). For these reasons, this variant has been classified as Pathogenic. -
