We report a patient from a family with autosomal dominant hypocalcaemia who also had prednisolone‐treated Langerhans’ cell histiocytosis and familial genetic studies identifying a novel calcium‐sensing receptor (CASR ) mutation. We describe an approach to define pathogenicity of a genetic variation of uncertain significance and postulate that bisphosphonates may have paradoxically increased fracture risk in our patient.
