The p.S1266I variant (also known as c.3797G>T or3916G>T), located in coding exon 9 of the BRCA1 gene, results from a G to T substitution at nucleotide position 3797. The serine at codon 1266 is replaced by isoleucine, an amino acid with dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. This amino acid position is moderately conserved in available vertebrate species. In addition, this alteration is predicted to be benign and deleterious by PolyPhen and SIFT in silico analyses, respectively.Since supporting evidence is limited at this time, the clinical significance ofp.S1266Iremains unclear.

The p.S1266I variant (also known as c.3797G>T or3916G>T), located in coding exon 9 of the BRCA1 gene, results from a G to T substitution at nucleotide position 3797. The serine at codon 1266 is replaced by isoleucine, an amino acid with dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. This amino acid position is moderately conserved in available vertebrate species. In addition, this alteration is predicted to be benign and deleterious by PolyPhen and SIFT in silico analyses, respectively.Since supporting evidence is limited at this time, the clinical significance ofp.S1266Iremains unclear.

This missense variant replaces serine with isoleucine at codon 1266 of the BRCA1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified 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)

This variant is denoted BRCA1 c.3797G>T at the cDNA level, p.Ser1266Ile (S1266I) at the protein level, and results in the change of a Serine to an Isoleucine (AGC>ATC). Using alternate nomenclature, this variant would be defined as BRCA1 3916G>T. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA1 Ser1266Ile was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Serine and Isoleucine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. BRCA1 Ser1266Ile occurs at a position that is not conserved and is not located in a known functional domain (UniProt, Paul 2014). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether BRCA1 Ser1266Ile is pathogenic or benign. We consider it to be 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. So this date may be different from the date of the “most recent submission” reported at the top of this page.
