dbSNP rs1300178646: MORN3:p.Trp94Gly (chr12-121659214-A-C) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_173855.5(MORN3):c.280T>G(p.Trp94Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000744 in 1,612,972 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. W94R) has been classified as Uncertain significance.
