Genetic Variant OSR2:p.Thr168Met (chr8-98949455-C-T) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2

The NM_001142462.3(OSR2):c.503C>T(p.Thr168Met) variant causes a missense change. The variant allele was found at a frequency of 0.0000235 in 1,613,696 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. T168R) has been classified as Uncertain significance.
