Description

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1254 of the C3 protein (p.Arg1254His). This variant is present in population databases (rs571907143, gnomAD 0.007%). This missense change has been observed in individual(s) with IgA nephropathy (PMID: 35685318). ClinVar contains an entry for this variant (Variation ID: 2397781). 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 not expected to disrupt C3 protein function with a negative predictive value of 80%. 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.
