Description

The p.T309I variant (also known as c.926C>T), located in coding exon 4 of the BARD1 gene, results from a C to T substitution at nucleotide position 926. The threonine at codon 309 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
