dbSNP rs200222766: PTCD3:p.Pro97Ala (chr2-86116578-C-G) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_017952.6(PTCD3):c.289C>G(p.Pro97Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00000206 in 1,457,120 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. P97S) has been classified as Uncertain significance.
