Genetic Variant ZNF77:p.His454Arg (chr19-2933766-T-C) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_021217.3(ZNF77):c.1361A>G(p.His454Arg) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,892 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. H454L) has been classified as Uncertain significance.
