dbSNP rs1486171671: FAM83H:p.Arg1055Cys (chr8-143726298-G-A) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2

The NM_198488.5(FAM83H):c.3163C>T(p.Arg1055Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000143 in 1,611,976 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. R1055H) has been classified as Uncertain significance.
