Genetic Variant TC2N:p.Arg408Cys (chr14-91785302-G-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_001128596.3(TC2N):c.1222C>T(p.Arg408Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000868 in 1,613,640 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R408H) has been classified as Uncertain significance.
