Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001142578.2(ZNF780A):c.1889G>A(p.Arg630His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000242 in 1,613,710 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. R630C) has been classified as Uncertain significance.

The c.1892G>A (p.R631H) alteration is located in exon 6 (coding exon 4) of the ZNF780A gene. This alteration results from a G to A substitution at nucleotide position 1892, causing the arginine (R) at amino acid position 631 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
