Variant summary

Our verdict is Benign. Variant got -18 ACMG points: 2P and 20B. PM5BP4_StrongBP6_Very_StrongBS1BS2

The NM_139242.4(MTFMT):​c.16C>T​(p.Arg6Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00925 in 1,429,500 control chromosomes in the GnomAD database, including 80 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict 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. R6P) has been classified as Likely pathogenic.
