Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The NM_001372076.1(PAX9):c.689G>T(p.Arg230Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000062 in 1,451,064 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R230H) has been classified as Uncertain significance.

Submissions by phenotype
not provided    Uncertain:1 
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; Not observed at significant frequency in large population cohorts (gnomAD) -
Hypodontia    Uncertain:1 
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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). This variant has not been reported in the literature in individuals with PAX9-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with leucine at codon 230 of the PAX9 protein (p.Arg230Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. -
