Study of DNA Copy Numbers Variations and Gene Expression Profile of Bone Marrow Plasma Cells From MGUS and SMM.

2014-08-27 03:15:30 | BioPortfolio

Summary

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.

Medical and Biotech [MESH] Definitions

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)
