Genes affected

(HGNC:):

NDUFV1-DT (HGNC:26915): (NDUFV1 divergent transcript)

NDUFV1 (HGNC:7716): (NADH:ubiquinone oxidoreductase core subunit V1) The mitochondrial respiratory chain provides energy to cells via oxidative phosphorylation and consists of four membrane-bound electron-transporting protein complexes (I-IV) and an ATP synthase (complex V). This gene encodes a 51 kDa subunit of the NADH:ubiquinone oxidoreductase complex I; a large complex with at least 45 nuclear and mitochondrial encoded subunits that liberates electrons from NADH and channels them to ubiquinone. This subunit carries the NADH-binding site as well as flavin mononucleotide (FMN)- and Fe-S-biding sites. Defects in complex I are a common cause of mitochondrial dysfunction; a syndrome that occurs in approximately 1 in 10,000 live births. Mitochondrial complex I deficiency is linked to myopathies, encephalomyopathies, and neurodegenerative disorders such as Parkinson's disease and Leigh syndrome. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 11-67606525-C-CT is Benign according to our data. Variant chr11-67606525-C-CT is described in ClinVar as [Likely_benign]. Clinvar id is 1195099.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0113 (1717/152202) while in subpopulation NFE AF= 0.0174 (1184/67998). AF 95% confidence interval is 0.0166. There are 12 homozygotes in gnomad4. There are 790 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 12 gene
