Genetic Variant ZNF774:p.Arg198Cys (chr15-90360423-C-T) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001004309.3(ZNF774):c.592C>T(p.Arg198Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000167 in 1,613,684 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R198G) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.592C>T (p.R198C) alteration is located in exon 4 (coding exon 3) of the ZNF774 gene. This alteration results from a C to T substitution at nucleotide position 592, causing the arginine (R) at amino acid position 198 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
