Genetic Variant ANKFN1:p.Arg95Ser (chr17-56350860-C-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001370326.1(ANKFN1):c.283C>A(p.Arg95Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00007 in 1,613,712 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 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. R95C) has been classified as Uncertain significance.
