Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM5BP4_Moderate
The NM_007348.4(ATF6):c.1018G>A(p.Ala340Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,612,826 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 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. A340P) has been classified as Likely pathogenic.

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1016706). This variant has not been reported in the literature in individuals affected with ATF6-related conditions. This variant is present in population databases (rs749537392, gnomAD 0.02%). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 340 of the ATF6 protein (p.Ala340Thr). -
