Paget's disease of bone (PDB) is a chronic disorder of bone metabolism, which typically results in enlarged and deformed bones in one or more regions of the skeleton. The aetiology of PDB has remained unknown for several decades, but either environmental or genetic factors have been implicated. The former mainly concern the presence of a slow-acting viral infection, a condition that may be present for many years before symptoms appear. However, there are also several data supporting a hereditary hypothesis, since in up to40%of patients the disease may appear in more than one family member. The genetic architecture of PDB is incompletely understood, but recent evidence suggests that the disease may be caused by a combination of rare variants in genes such as SQSTM1 (detected in up to 50% of familial cases of PDB) and more common variants (i.e. polymorphisms) in genes such as CSF1, TNFRSF11A, OPTN and TM7SF4.

Abstract
Paget's disease of bone (PDB) is a chronic disorder of bone metabolism, which typically results in enlarged and deformed bones in one or more regions of the skeleton. The aetiology of PDB has remained unknown for several decades, but either environmental or genetic factors have been implicated. The former mainly concern the presence of a slow-acting viral infection, a condition that may be present for many years before symptoms appear. However, there are also several data supporting a hereditary hypothesis, since in up to40%of patients the disease may appear in more than one family member. The genetic architecture of PDB is incompletely understood, but recent evidence suggests that the disease may be caused by a combination of rare variants in genes such as SQSTM1 (detected in up to 50% of familial cases of PDB) and more common variants (i.e. polymorphisms) in genes such as CSF1, TNFRSF11A, OPTN and TM7SF4.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
