Genetic Variant NIF3L1:p.Val113Met (chr2-200892280-G-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001369441.2(NIF3L1):c.337G>A(p.Val113Met) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,613,990 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V113L) has been classified as Uncertain significance.
