The purpose of this study is to describe DNA copy number variations and gene expression profiles of bone marrow plasma cells of monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). The final objective is to search for correlations with the risk of progression in order to establish a predictive model of early malignant transformation.

RATIONALE: Monoclonal antibodies, such as rituximab, can block abnormal cell growth in different ways. Some block the ability of abnormal cells to grow and spread. Others find abnormal cel...
Monoclonal gammopathy of undetermined significance (MGUS) occurs in approximately 3% of persons 50 years of age or older.
In rheumatological practice monoclonal gammopathy of undetermined significance (MGUS) is a common incidental finding. Several rheumatic inflammatory diseases are known to have an elevated risk of MGU...
To investigate the words and descriptions used by haematology healthcare professionals (HCPs) to describe monoclonal gammopathy of undetermined significance (MGUS) to their patients.
Exposure to air pollution activates the innate immune system and influences the adaptive immune system in experimental settings. We investigated the association of residential long-term exposure to pa...
IgA vasculitis (Henoch-Schonlein purpura) is a small vessel systemic vasculitis involving IgA immunoglobulin polyclonal activation(1) . Monoclonal gammopathy of cutaneous significance is a subgroup of...
Conditions characterized by the presence of M protein (Monoclonal protein) in serum or urine without clinical manifestations of plasma cell dyscrasia.
A cutaneous necrobiotic disorder characterized by firm, yellow plaques or nodules, often in a periorbital distribution. It is often accompanied by an elevated ERYTHROCYTE SEDIMENTATION RATE; LEUKOPENIA; and MONOCLONAL GAMMOPATHY (IgG-kappa type) and systemic involvement.
A connective tissue disorder characterized by widespread thickening of SKIN with a cobblestone-like appearance. It is caused by proliferation of FIBROBLASTS and deposition of MUCIN in the DERMIS in the absence of thyroid disease. Most scleromyxedema cases are associated with a MONOCLONAL GAMMOPATHY, immunoglobulin IgG-lambda.
Abnormal immunoglobulins synthesized by atypical cells of the MONONUCLEAR PHAGOCYTE SYSTEM. Paraproteins containing only light chains lead to Bence Jones paraproteinemia, while the presence of only atypical heavy chains leads to heavy chain disease. Most of the paraproteins show themselves as an M-component (monoclonal gammopathy) in electrophoresis. Diclonal and polyclonal paraproteins are much less frequently encountered.
A multisystemic disorder characterized by a sensorimotor polyneuropathy (POLYNEUROPATHIES), organomegaly, endocrinopathy, monoclonal gammopathy, and pigmentary skin changes. Other clinical features which may be present include EDEMA; CACHEXIA; microangiopathic glomerulopathy; pulmonary hypertension (HYPERTENSION, PULMONARY); cutaneous necrosis; THROMBOCYTOSIS; and POLYCYTHEMIA. This disorder is frequently associated with osteosclerotic myeloma. (From Adams et al., Principles of Neurology, 6th ed, p1335; Rev Med Interne 1997;18(7):553-62)
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
