5-112842344-C-T
Variant summary
Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6_Very_StrongBP7
The NM_000038.6(APC):c.6750C>T(p.Gly2250Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000384 in 1,613,880 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 Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. G2250G) has been classified as Benign.

Familial adenomatous polyposis 1    Benign:2 
- -
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
not provided    Benign:2 
- -
- -
Hereditary cancer-predisposing syndrome    Benign:2 
- -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
