Variant summary

Our verdict is Pathogenic. The variant received 17 ACMG points: 17P and 0B. PM1PM2PP2PP3_StrongPP5_Very_Strong

The NM_001151.4(SLC25A4):c.368C>A(p.Ala123Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,614,082 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. A123A) has been classified as Likely benign.

Genes affected

SLC25A4 (HGNC:10990): (solute carrier family 25 member 4) This gene is a member of the mitochondrial carrier subfamily of solute carrier protein genes. The product of this gene functions as a gated pore that translocates ADP from the cytoplasm into the mitochondrial matrix and ATP from the mitochondrial matrix into the cytoplasm. The protein forms a homodimer embedded in the inner mitochondria membrane. Mutations in this gene have been shown to result in autosomal dominant progressive external opthalmoplegia and familial hypertrophic cardiomyopathy. [provided by RefSeq, Jun 2013]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 17 ACMG points.

PM1

In a chain ADP/ATP translocase 1 (size 296) in uniprot entity ADT1_HUMAN there are 12 pathogenic changes around while only 3 benign (80%) in NM_001151.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 11 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 1.8742 (below the threshold of 3.09). Trascript score misZ: 2.2652 (below the threshold of 3.09). GenCC associations: The gene is linked to mitochondrial DNA depletion syndrome 12A (cardiomyopathic type), autosomal dominant, mitochondrial disease, progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 2, mitochondrial DNA depletion syndrome 12B (cardiomyopathic type), autosomal recessive, Fontaine progeroid syndrome, Leigh syndrome, Sengers syndrome, autosomal dominant progressive external ophthalmoplegia.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.984

PP5

Variant 4-185145020-C-A is Pathogenic according to our data. Variant chr4-185145020-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 18249.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
