Genes affected

SURF1 (HGNC:11474): (SURF1 cytochrome c oxidase assembly factor) This gene encodes a protein localized to the inner mitochondrial membrane and thought to be involved in the biogenesis of the cytochrome c oxidase complex. The protein is a member of the SURF1 family, which includes the related yeast protein SHY1 and rickettsial protein RP733. The gene is located in the surfeit gene cluster, a group of very tightly linked genes that do not share sequence similarity, where it shares a bidirectional promoter with SURF2 on the opposite strand. Defects in this gene are a cause of Leigh syndrome, a severe neurological disorder that is commonly associated with systemic cytochrome c oxidase deficiency. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr9-133351923-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 3339531.

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 2 curated benign missense variants. Gene score misZ: -0.68006 (below the threshold of 3.09). Trascript score misZ: -1.3185 (below the threshold of 3.09). GenCC associations: The gene is linked to mitochondrial complex IV deficiency, nuclear type 1, Leigh syndrome, mitochondrial disease, Charcot-Marie-Tooth disease type 4K, Leigh syndrome with leukodystrophy, Leigh syndrome with cardiomyopathy.
