Genes affected
NDUFS1 (HGNC:7707): (NADH:ubiquinone oxidoreductase core subunit S1) The protein encoded by this gene belongs to the complex I 75 kDa subunit family. Mammalian complex I is composed of 45 different subunits. It locates at the mitochondrial inner membrane. This protein has NADH dehydrogenase activity and oxidoreductase activity. It transfers electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. This protein is the largest subunit of complex I and it is a component of the iron-sulfur (IP) fragment of the enzyme. It may form part of the active site crevice where NADH is oxidized. Mutations in this gene are associated with complex I deficiency. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 6 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_005006.7
PM2
?
Very rare variant in population databases, with high coverage;
PM4
?
Nonframeshift variant in NON repetitive region in NM_005006.7. Strenght limited to Supporting due to length of the change: 1aa.
PP5
?
Variant 2-206146971-AATG-A is Pathogenic according to our data. Variant chr2-206146971-AATG-A is described in ClinVar as [Pathogenic]. Clinvar id is 14230.Status of the report is no_assertion_criteria_provided, 0 stars.
