Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_000038.6(APC):c.6457G>T(p.Asp2153Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,460,944 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. D2153N) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 05, 2021 | 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with APC-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with tyrosine at codon 2153 of the APC protein (p.Asp2153Tyr). The aspartic acid residue is highly conserved and there is a large physicochemical difference between aspartic acid and tyrosine. - |
