Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_000204.5(CFI):āc.1643A>Gā(p.Glu548Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,862 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 (ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E548Q) has been classified as Likely benign.

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 17, 2023 | This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 548 of the CFI protein (p.Glu548Gly). This variant is present in population databases (rs771446070, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with CFI-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CFI protein function. 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. - |
