Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_001367624.2(ZNF469):c.4258G>A(p.Glu1420Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000555 in 1,550,110 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 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. E1420V) has been classified as Uncertain significance.

Submissions by phenotype
not provided Uncertain:2
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1392 of the ZNF469 protein (p.Glu1392Lys). This variant is present in population databases (rs387907063, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ZNF469-related conditions. ClinVar contains an entry for this variant (Variation ID: 1029104). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Cardiovascular phenotype Uncertain:1
The c.4174G>A (p.E1392K) alteration is located in exon 2 (coding exon 2) of the ZNF469 gene. This alteration results from a G to A substitution at nucleotide position 4174, causing the glutamic acid (E) at amino acid position 1392 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Brittle cornea syndrome 1 Uncertain:1
This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
