Variant summary: BRCA1 c.1922T>C (p.Ile641Thr) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.1e-06 in 245800 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1922T>C in individuals affected with Hereditary Breast and Ovarian Cancer and no experimental evidence demonstrating its impact on protein function have been reported. Six ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. (less)

In the published literature, this variant has been reported to be located in a region of the BRCA1 gene that is tolerant to missense sequence changes (PMID: 31911673 (2020)). In a large-scale breast cancer association study, the variant was observed in an individual with breast cancer (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRCA1)). The frequency of this variant in the general population, 0.0000071 (2/282404 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. (less)

This missense variant replaces isoleucine with threonine at codon 641 of the BRCA1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been detected in a breast cancer case-control meta-analysis in 3/60466 cases and 0/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA1_004716), and this variant also has been reported in 1 individual age 70 years or older without cancer in the FLOSSIES database (https://whi.color.com/variant/17-41245626-A-G). This variant has been identified in 2/282404 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. (less)

Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals with personal or family history of breast and ovarian cancer (Leiden Open Variant Database individual #00272017; Color internal data) and an individual age 70 years or older without cancer by FLOSSIES. This variant has been identified in 2/282404 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. (less)

The p.I641T variant (also known as c.1922T>C), located in coding exon 9 of the BRCA1 gene, results from a T to C substitution at nucleotide position 1922. The isoleucine at codon 641 is replaced by threonine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

The BRCA1 c.1922T>C (p.I641T) variant has been reported in heterozygosity in at least three individuals with breast cancer (PMID: 33471991). This variant was observed in 2/128808 chromosomes in the European (non-Finnish) population according to the Genome Aggregation Database (http://gnomad.broadinstitute.org, PMID: 32461654) and has been reported in ClinVar (Variation ID: 182138). In silico tools suggest the impact of the variant on protein function is deleterious, though these predictions have not been confirmed by functional studies. Based on the current evidence available, this variant is interpreted as a variant of uncertain significance. (less)

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 641 of the BRCA1 protein (p.Ile641Thr). This variant is present in population databases (rs730881474, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 182138). 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 BRCA1 protein function with a negative predictive value of 95%. 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. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number.
