Breast cancer pertinent cancer susceptibility
Gene: CDH1
After NHS Genomic Medicine Service consideration, this gene has not been made Green and has been rated as Red. Additional comments from reviewing GLHs: 'There is a well established association of this gene withpredisposition to lobular breast cancer, but it presents huge problems when it is identified outside the context of a relevant family history. The UK Cancer genetics community do not want to add this gene to any general breast cancer susceptibility panels hence are extremely reluctant to test this gene outside of the already existing R215 criteria'Created: 2 May 2024, 1:54 p.m. | Last Modified: 2 May 2024, 1:54 p.m.
Panel Version: 2.9
Comment on list classification: New gene added to this panel by Lauma Freimane. Germline heterozygous variants have been found in diffuse gastric and lobular breast cancer syndrome. Patients may develop lobular breast cancer only or lobular breast cancer with gastric cancer. Lobular carcinoma of the breast has been reported in up to 60% of female carriers.
Overall there is sufficient evidence to classify this as a breast cancer susceptibility gene. However, it should be noted that this gene is already covered by a targeted panel, R215 CDH1-related cancer syndrome. Will leave the decision with the GMS expert group as to whether this phenotype should also be covered by this panel.Created: 24 Jul 2023, 9:27 a.m. | Last Modified: 24 Jul 2023, 9:27 a.m.
