Genetic Variant FAM110B:p.Arg204His (chr8-58146841-G-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001377989.1(FAM110B):c.611G>A(p.Arg204His) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,612,898 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. R204L) has been classified as Uncertain significance.
