Genes affected

SLC25A15 (HGNC:):

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

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BP6: Variant 13-40789460-C-G is Benign according to our data. Variant chr13-40789460-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 312169.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Likely_benign=1, Uncertain_significance=1}.
• BS2: High Homozygotes in GnomAd4 at 7 gene
