Description

The p.T664A variant (also known as c.1990A>G), located in coding exon 12 of the ATM gene, results from an A to G substitution at nucleotide position 1990. The threonine at codon 664 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. 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.
