Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PS1PM2PP3_Strong
The NM_001113378.2(FANCI):c.1264G>A(p.Gly422Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000233 in 1,614,002 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 nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in Lovd.

Fanconi anemia Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 422 of the FANCI protein (p.Gly422Arg). This variant is present in population databases (rs146040966, gnomAD 0.02%). This missense change has been observed in individual(s) with Fanconi anemia (PMID: 17452773, 23613520). ClinVar contains an entry for this variant (Variation ID: 408241). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt FANCI protein function with a positive predictive value of 80%. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
