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 made for transcript

Verdict is Benign. Variant got -11 ACMG points.

PM1
In a chain Surfeit locus protein 1 (size 299) in uniprot entity SURF1_HUMAN there are 17 pathogenic changes around while only 2 benign (89%) in NM_003172.4
BP4
Computational evidence support a benign effect (MetaRNN=0.0063804686).
BP6
Variant 9-133352593-C-G is Benign according to our data. Variant chr9-133352593-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 139375.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Benign=2, Uncertain_significance=1}.
BA1
GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.142 is higher than 0.05.
