Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_000465.4(BARD1):āc.2105T>Cā(p.Ile702Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,868 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I702M) has been classified as Likely benign.

Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 02, 2023 | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 702 of the BARD1 protein (p.Ile702Thr). This variant is present in population databases (rs752114855, gnomAD 0.003%). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 629851). This variant has not been reported in the literature in individuals affected with BARD1-related conditions. - |
