Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_000038.6(APC):c.10G>T(p.Ala4Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,613,640 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. A4P) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Apr 18, 2019 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 26, 2023 | The p.A4S variant (also known as c.10G>T), located in coding exon 1 of the APC gene, results from a G to T substitution at nucleotide position 10. The alanine at codon 4 is replaced by serine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, in silico predictors for this gene do not accurately predict pathogenicity. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
Familial adenomatous polyposis 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 02, 2023 | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt APC protein function. ClinVar contains an entry for this variant (Variation ID: 487049). This variant has not been reported in the literature in individuals affected with APC-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 4 of the APC protein (p.Ala4Ser). - |
