Genetic Variant PHOSPHO2:p.Val121Leu (chr2-169701332-G-T) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_001008489.4(PHOSPHO2):c.361G>T(p.Val121Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,612,934 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. V121M) has been classified as Uncertain significance.
