Genetic Variant ZNF671:p.Cys194Tyr (chr19-57721505-C-T) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_024833.3(ZNF671):c.581G>A(p.Cys194Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,614,100 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict 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. C194R) has been classified as Uncertain significance.

The c.581G>A (p.C194Y) alteration is located in exon 4 (coding exon 4) of the ZNF671 gene. This alteration results from a G to A substitution at nucleotide position 581, causing the cysteine (C) at amino acid position 194 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
