A Novel <i>ATM</i> Pathogenic Variant in an Italian Woman with Gallbladder Cancer
Gallbladder carcinoma (GBC) is one of the most aggressive malignancies with poor prognosis and a high fatality rate. The disease presents in advanced stages where the treatment is ineffective. Regarding GBC pathogenesis, as with other neoplasia, this tumor is a multifactorial disorder involving diff...
