Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP3_Strong
The NM_000419.5(ITGA2B):c.1214T>G(p.Ile405Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,000 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. I405T) has been classified as Pathogenic.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 25, 2023 | 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ITGA2B protein function. This variant has not been reported in the literature in individuals affected with ITGA2B-related conditions. This variant is present in population databases (rs75622274, gnomAD 0.003%). This sequence change replaces isoleucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 405 of the ITGA2B protein (p.Ile405Ser). - |
