dbSNP rs867228239: PAPOLB:p.Glu592Gln (chr7-4860037-C-G) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_020144.5(PAPOLB):c.1774G>C(p.Glu592Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,668 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/17 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. E592K) has been classified as Uncertain significance.
