Genetic Variant NM_173826.4:c.650G>A (chr3-44392932-G-A) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_173826.4(TCAIM):c.650G>A(p.Arg217His) variant causes a missense change. The variant allele was found at a frequency of 0.000356 in 1,612,990 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. R217G) has been classified as Uncertain significance.
