A total of 611 asymptomatic family members from 86 out of 105 index patients harboring SDHB mutations underwent genetic testing. From this cohort, 328 were found to likewise have an SDHB mutation. Screened individuals totaled 241, with 87 not screened due to refusal. Of the screened patients, 40 were diagnosed with PHEO/PGL histologically, or via a combination of positive biochemistry and imaging studies. Two out of the 105 index patients were excluded from analyses due to lack of clinical data.
