Blood and urine samples are collected for evaluation of kidney and liver function and determination of the presence of a monoclonal protein. Imaging studies such as echocardiography and an ultrasound of the abdomen will be performed. A CT scan, magnetic resonance imaging (MRI) or positron emission tomography (PET) may also be indicated. In patients with LCDD, a biopsy of the affected organ will show deposited light chains. A bone marrow biopsy will be done in order to rule out multiple myeloma. Treatment
Decreasing production of the organ-damaging light chains is the treatment goal. Options include chemotherapy using bortezomib, autologous stem cell transplantation, immunomodulatory drugs, and kidney transplant.There is no standard treatment for LCDD. High-dose melphalan in conjunction with autologous stem cell transplantation has been used in some patients. A regimen of bortezomib and dexamethasone has also been examined. Prognosis
The median time to progression to end stage renal disease is 2.7 years. After 5 years, about 37% of patients with LCDD are alive and do not have end stage renal disease. References

Emedicine
Majeed syndrome is an inherited skin disorder characterized by chronic recurrent multifocal osteomyelitis, congenital dyserythropoietic anemia and a neutrophilic dermatosis. It is classified as an autoinflammatory bone disorder. The condition is found in people with two defective copies (autosomal recessive inheritance) of the LPIN2 gene. LPIN2 encodes lipin-2 which is involved in lipid metabolism. The pathogenesis of this mutation with the clinical manifestations has not been elucidated. Treatments
Treatments for this disorder are often based on what symptoms are present in the patient. Most commonly prescribed treatments include nonsteroidal anti-inflammatory drugs (NSAIDs), as well as physical therapy in order to prevent from muscle atrophy in patients. Red blood transfusions could also be done for patients with severe congenital dyserythrypoietic anemia (CDA). See also
