Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_001184.4(ATR):c.4846T>G(p.Ser1616Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000102 in 1,579,216 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1616P) has been classified as Uncertain significance.

This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1616 of the ATR protein (p.Ser1616Ala). This variant is present in population databases (rs201492267, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with ATR-related conditions. ClinVar contains an entry for this variant (Variation ID: 425314). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
