Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS1

The NM_001985.3(ETFB):c.521G>A(p.Arg174His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000247 in 1,608,744 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R174C) has been classified as Uncertain significance.

Genes affected

ETFB (HGNC:3482): (electron transfer flavoprotein subunit beta) This gene encodes electron-transfer-flavoprotein, beta polypeptide, which shuttles electrons between primary flavoprotein dehydrogenases involved in mitochondrial fatty acid and amino acid catabolism and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. The gene deficiencies have been implicated in type II glutaricaciduria. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -16 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011149138).

BP6

Variant 19-51346976-C-T is Benign according to our data. Variant chr19-51346976-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 203699.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00123 (187/152200) while in subpopulation AFR AF = 0.00438 (182/41506). AF 95% confidence interval is 0.00386. There are 1 homozygotes in GnomAd4. There are 88 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
