Variant summary

Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The NM_024867.4(SPEF2):c.220G>A(p.Gly74Ser) variant causes a missense change. The variant allele was found at a frequency of 0.05 in 1,613,610 control chromosomes in the GnomAD database, including 2,246 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Synonymous variant affecting the same amino acid position (i.e. G74G) has been classified as Likely benign.
