Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2
The NM_012123.4(MTO1):āc.1086C>Gā(p.Ile362Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000502 in 1,614,034 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā ā ).
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]
Computational evidence support a benign effect (MetaRNN=0.022194862).
BP6
Variant 6-73480083-C-G is Benign according to our data. Variant chr6-73480083-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 414886.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 = 0.00281 (428/152220) while in subpopulation AFR AF= 0.00953 (396/41542). AF 95% confidence interval is 0.00876. There are 3 homozygotes in gnomad4. There are 195 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
