Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_000038.6(APC):āc.3484T>Cā(p.Tyr1162His) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,784 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 (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y1162C) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 17, 2022 | The p.Y1162H variant (also known as c.3484T>C), located in coding exon 15 of the APC gene, results from a T to C substitution at nucleotide position 3484. The tyrosine at codon 1162 is replaced by histidine, an amino acid with similar properties. This amino acid position is conserved. 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 | Jan 04, 2024 | This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 1162 of the APC protein (p.Tyr1162His). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with APC-related conditions. ClinVar contains an entry for this variant (Variation ID: 659894). 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 with a negative predictive value of 95%. 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. - |
