To mitigate the mortality of this disease, it is recommended the evaluation of multiple high-penetrance genes.
We used a multi-gene panel testing to identify germline variants in a unique case of a breast cancer patient with a family history of five different neoplasm types. The patient, at the age of 50 years, was diagnosed with a high-grade cribriform ductal carcinoma in situ in her left breast.
We identified two heterozygous mutations, one classified as pathogenic/likely pathogenic in RAD50 and the other classified as a variant of uncertain significance (VUS) in ATM.
In conclusion, the use of the multi-gene panel leads to the identification of a double heterozygous mutation in RAD50 and ATM in a breast cancer patient from a Peruvian family with several cancer types. This data helps our physician team and the patient to choose a treatment following the post-test genetic counseling.
