Genetic Variant SPRED2:p.Arg306His (chr2-65313841-C-T) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. PP2BP4_Moderate

The NM_181784.3(SPRED2):c.917G>A(p.Arg306His) variant causes a missense change. The variant allele was found at a frequency of 0.0000354 in 1,612,128 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. R306L) has been classified as Uncertain significance.
