Invitae | RCV003041486 | SCV003445262 | uncertain significance | Hyper-IgM syndrome type 1 | 2022-04-01 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 252 of the CD40LG protein (p.Gly252Asp). This missense change has been observed in individual(s) with hyper IgM syndrome (PMID: 23653974). 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 CD40LG 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. |
