Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2
The NM_001135998.3(NDUFB11):c.427G>A(p.Asp143Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000091 in 1,208,819 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 5 hemizygotes in GnomAD. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D143H) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
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
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. -
