Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001145365.3(ZNF652):​c.1046T>G​(p.Val349Gly) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. 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. V349I) has been classified as Uncertain significance.

The c.1046T>G (p.V349G) alteration is located in exon 3 (coding exon 2) of the ZNF652 gene. This alteration results from a T to G substitution at nucleotide position 1046, causing the valine (V) at amino acid position 349 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
