Multiple Myeloma (MM) is an incurable plasma cell malignancy with a complex and incompletely understood molecular pathogenesis. Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smouldering Multiple Myeloma (SMM) precede MM, with variable risks and rates of disease progression. The continuing high relapse and death rate in MM cases has prompted research into more accurate prognostic markers to predict progression from MGUS and SMM to MM, as well as identify MM cases with aggressive disease, in order to begin early, targeted and effective therapeutic intervention. Many studies have focused on utilising current markers more effectively, including M-protein, serum-free light chain ratio, …

Thiopurine methyltransferase (TPMT) is a cytosolic enzyme that catalyses the S- methylation of aromatic and sulphydryl compounds known as the thiopurines. These therapeutic agents are used in the treatment of acute lymphoblastic leukemia, autoimmune disorders, inflammatory bowel disease and organ transplant recipients.
Erythrocyte TPMT activity is polymorphic and patients with intermediate or deficient TPMT are at significant risk for excessive toxicity after receiving ‘standard’ doses of thiopurine medications. The activity of TPMT is inherited as an autosomal co-dominant trait. Several mutations in the TPMT gene have been described that correlate with a low activity phenotype. Three mutations G238C, G460A and …

Venous thrombosis is a serious health problem affecting 1 in 1000 individuals annually. Until recently the pathogenic factors underlying thrombosis were associated with genetic defects in protein C, protein S and antithrombin III. However these were recognised in fewer than 5-10% of thrombotic patients. A breakthrough was made with the discovery of activated protein C resistance (APCr) which is associated in 90% of cases v/herein a G-->A transition in the factor V gene results in an abnormal molecule, Factor V Leiden. APCr is a major risk factor for thrombosis being present in 20-60% of thrombotic patients. Recently a G-^A …
