Genes affected
SLC25A15 (HGNC:10985): (solute carrier family 25 member 15) This gene is a member of the mitochondrial carrier family. The encoded protein transports ornithine across the inner mitochondrial membrane from the cytosol to the mitochondrial matrix. The protein is an essential component of the urea cycle, and functions in ammonium detoxification and biosynthesis of the amino acid arginine. Mutations in this gene result in hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. There is a pseudogene of this locus on the Y chromosome.[provided by RefSeq, May 2009]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

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 15 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: 0.10098 (below the threshold of 3.09). Trascript score misZ: 1.3225 (below the threshold of 3.09). GenCC associations: The gene is linked to ornithine translocase deficiency.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.99
PP5
Variant 13-40809585-G-A is Pathogenic according to our data. Variant chr13-40809585-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 5996.Status of the report is criteria_provided_single_submitter, 1 stars.
