Genetic Variant COPS2:p.Ala419Ser (chr15-49128027-C-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_004236.4(COPS2):c.1255G>T(p.Ala419Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,670 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict 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. A419T) has been classified as Uncertain significance.
