Despite mutations in SQSTM1 gene have been detected in up to 50% of patients with familial Paget’s disease of bone (PDB), their prevalence is low in sporadic PDB, likely due to the presence of additional predisposition genes. Recently, at least seven genes were associated with PDB in genome-wide-association studies, including polymorphic variation in OPTN,encoding for optineurin. In particular, a single OPTN variant (rs1561570) was highly associated with...

We previously evidenced a reduced response to i.v. pamidronate in Q15STM1 mutation carriers (Q15STM1+) with Paget’s disease of bone (PDB). In order to confirm and extend this observation, we investigated the effect of Q15STM1 mutation and polymorphisms in three genes associated with PDB (TNFRSF11A; OPTN; TNFRSF11B) on the response to bisphosphonates. First, a retrospective study was performed in 335 patients treated wi...
