Brief Summary
Paget's disease of the bone (PDB) is a skeletal disorder with a strong genetic component which can be associated with various complications such as pain, bone deformity, arthritis and deafness. Recent advances in understanding the genetic determinants of PDB offer the prospect of developing a genetic profiling test which can be offered to people with a parent or sibling with PDB to determine how likely they are to develop the disease themselves. The aim of the study is to perform genetic testing for variants associated with PDB in people aged 45 and above who have a parent or sibling (first degree relative) with the disease. The Investigators will assess how well genetic profiling performs in predicting PDB by performing an imaging technique called a radionuclide bone scan which is a very sensitive way of detecting early PDB. This scan will be performed on entry to the study and again after five years. The reason for performing two scans five years apart because PDB becomes more common with age and so this will allow the Investigators to give an accurate indication of how good the genetic profiling test is in people at different ages. In addition to genetic profiling the investigators will analyse blood samples for biochemical markers of PDB and also test saliva and stool samples for the microbiome profile since its thought that this may influence risk of the disease as well. In the longer term the investigators hope the study will allow them to develop a blood test to stratify for risk of PDB and use bone scans only in people who the clinicians think are at highest risk of developing the disease. This will allow people with PDB to be picked up early allowing treatment to be given in a timely manner.

Outcome Measures
Primary Outcomes (3)
PRIMARY ENDPOINTS - Identify Genetic Markers that are associated with the increased presence of PDB lesions in people with a family history of the disorder, as assessed by a radionuclide bone scan
Genetic and Transcriptome profile of each participant will be produced and analysed to determine if there is any association between specific genes and a increase in the presence of PDB lesions in people with a family history of the disorder. PDB lesions will be assessed by a radionuclide bone scan
5 years
Primary Endpoint (Participant arm): The proportion of patients that develop PDB-like bone lesions
The proportion of participants who have a family history of PDB that develop PDB-like bone lesions by the end of study assessed by radionuclide bone scan.
5 years
Primary Endpoint (Participant arm): T proportion of individuals that develop abnormalities suggestive of PDB
The primary endpoint will be to evaluate the proportion of individuals that develop biochemical or clinical abnormalities suggestive of PDB over a the 5-year duration of the trial
5 years

Study Arms (2)
Observational (With Bone Scan)
Individuals with a Family history of Paget's disease of bone (PDB) affecting first degree relative such as a parent or sibling that have not already diagnosed with PDB
Observational (Without Bone scan)
Individuals, that are spouses, friends and/or non blood relatives of the individuals with a family history of PDB.
