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

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a chain ADP/ATP translocase 1 (size 296) in uniprot entity ADT1_HUMAN there are 13 pathogenic changes around while only 4 benign (76%) in NM_001151.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.919
• PP5: Variant 4-185144963-A-G is Pathogenic according to our data. Variant chr4-185144963-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 18248.Status of the report is no_assertion_criteria_provided, 0 stars.
