Genes affected
NDUFB11 (HGNC:20372): (NADH:ubiquinone oxidoreductase subunit B11) The protein encoded by this gene is a subunit of the multisubunit NADH:ubiquinone oxidoreductase (complex I). Mammalian complex I is located at the mitochondrial inner membrane. This protein has NADH dehydrogenase activity and oxidoreductase activity. It transfers electrons from NADH to ubiquinone. Mutations in the human gene are associated with linear skin defects with multiple congenital anomalies 3 and mitochondrial complex I deficiency. [provided by RefSeq, Dec 2016]

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.457G>A (p.D153N) alteration is located in exon 3 (coding exon 3) of the NDUFB11 gene. This alteration results from a G to A substitution at nucleotide position 457, causing the aspartic acid (D) at amino acid position 153 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Mitochondrial complex I deficiency, nuclear type 30 Uncertain:1
Jun 13, 2019
Johns Hopkins Genomics, Johns Hopkins University
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This NDUFB11 variant has not been reported in ClinVar nor the literature, to our knowledge. Additionally, this variant (rs374083393) is rare (<0.1%) in a large population dataset (gnomAD: 1/201877 total alleles; 0.0004945%; no homozygotes; no hemizygotes). Two bioinformatic tool queried predict that this substitution would be probably damaging, and the aspartic acid residue at this position is evolutionarily conserved across all species assessed. Bioinformatic analysis predicts that this missense variant would not affect normal exon 3 splicing, although this has not been confirmed experimentally to our knowledge. The clinical significance of c.457G>A is uncertain at this time. -
