Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM2PM5PP2PP3_Strong

The NM_152707.4(SLC25A16):c.793C>G(p.Arg265Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,418 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R265H) has been classified as Uncertain significance.

Genes affected

SLC25A16 (HGNC:10986): (solute carrier family 25 member 16) This gene encodes a protein that contains three tandemly repeated mitochondrial carrier protein domains. The encoded protein is localized in the inner membrane and facilitates the rapid transport and exchange of molecules between the cytosol and the mitochondrial matrix space. This gene has a possible role in Graves' disease. [provided by RefSeq, Jul 2008]

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;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr10-68487193-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 224813.Status of the report is criteria_provided_single_submitter, 1 stars.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.57984 (below the threshold of 3.09). Trascript score misZ: -0.19574 (below the threshold of 3.09).

PP3

MetaRNN computational evidence supports a deleterious effect, 0.98
