Ambry Genetics RCV001026418 SCV001188795 uncertain significance Hereditary cancer-predisposing syndrome 2018-07-02 criteria provided, single submitter clinical testing The p.Q247H variant (also known as c.741G>C), located in coding exon 7 of the APC gene, results from a G to C substitution at nucleotide position 741. The glutamine at codon 247 is replaced by histidine, an amino acid with highly similar properties. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Color Diagnostics, LLC DBA Color Health RCV001026418 SCV001344822 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces glutamine with histidine at codon 247 of the APC protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
