chr6-73462030-G-C

Variant summary

Our verdict is Benign. Variant got -11 ACMG points: 1P and 12B. PP3BP4_StrongBP6_Very_Strong

The NM_012123.4(MTO1):ā€‹c.176G>Cā€‹(p.Gly59Ala) variant causes a missense change. The variant allele was found at a frequency of 0.000715 in 1,614,048 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā˜…ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G59C) has been classified as Uncertain significance.

Genes affected
MTO1 (HGNC:19261): (mitochondrial tRNA translation optimization 1) This gene encodes a mitochondrial protein thought to be involved in mitochondrial tRNA modification. The encoded protein may also play a role in the expression of the non-syndromic and aminoglycoside-induced deafness phenotypes associated with a specific mutation in the mitochondrial 12S rRNA gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 8: BayesDel_addAF, BayesDel_noAF, Cadd, Eigen, M_CAP, MutationAssessor, PROVEAN, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.028492749).
BP6
Variant 6-73462030-G-C is Benign according to our data. Variant chr6-73462030-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 540425.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
