Genetic Variant ZNF490:p.Val519Met (chr19-12580520-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_020714.3(ZNF490):c.1555G>A(p.Val519Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000155 in 1,609,154 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. V519L) has been classified as Uncertain significance.

The c.1555G>A (p.V519M) alteration is located in exon 5 (coding exon 5) of the ZNF490 gene. This alteration results from a G to A substitution at nucleotide position 1555, causing the valine (V) at amino acid position 519 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
