Genetic Variant SAMD3:p.Ala468Glu (chr6-130144680-G-T) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

The NM_001017373.4(SAMD3):c.1403C>A(p.Ala468Glu) variant causes a missense change. The variant allele was found at a frequency of 0.0000595 in 1,614,092 control chromosomes in the GnomAD database, including 3 homozygotes. 13/22 in silico tools predict 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. A468V) has been classified as Uncertain significance.
