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.

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.985 CDS is truncated, and there are 3 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 3-39383738-C-G is Pathogenic according to our data. Variant chr3-39383738-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 2961574.Status of the report is criteria_provided_single_submitter, 1 stars.

Submissions by phenotype

not provided Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 17, 2023For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with SLC25A38-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). 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). -
