Genetic Variant YTHDC1:p.Gly274Val (chr4-68337089-C-A) – ACMG Classification: Benign (-8 pts)

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_001031732.4(YTHDC1):c.821G>T(p.Gly274Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000372 in 1,613,900 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict 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. G274D) has been classified as Likely benign.
