-
- Chromosome 11/14 Translocation is a chromosomal disorder caused by an
- abnormal exchange of parts between chromosomes 11 and 14. Some of chromosome
- 11 is located on chromosome 14 or vice versa. This disorder is associated
- with certain types of leukemia.
-
- Symptoms
-
- Chromosome 11/14 Translocation is associated with certain types of leukemia.
- In leukemia, there is an unusually high level of white blood cells. There
- are different types of white blood cells. Some are called B cells, and
- others are called T cells. Chromosome 11/14 Translocation is linked
- especially with Chronic Lymphocytic Leukemia (generally involving the B cell)
- and T-cell Acute Lymphocytic Leukemia. Where the translocation is located on
- a chromosome usually determines which type of leukemia a person will get.
-
- Symptoms of these leukemias may include anemia causing loss of strength
- (asthenia), pallor, headache, ringing of the ears (tinnitus), labored,
- breathing (dyspnea), chest pain (angina), and swelling (edema). Hemorrhage,
- infections (generally bacterial such as sinusitis or pneumonia), fatigue,
- night sweats, fever, anorexia, or weight loss are other possible symptoms of
- leukemia. Swelling of the lymph nodes may also occur.
-
- Causes
-
- Chromosome 11/14 Translocation is caused by an exchange of parts between
- chromosomes 11 and 14. Some of chromosome 11 is located on chromosome 14 or
- vice versa. The reasons these chromosomes are abnormal is not understood.
- However, in some cases the cause may be genetic, possibly of autosomal
- dominant inheritance.
-
- Human traits, including the classic genetic diseases, are the product of
- the interaction of two genes, one received from the father and one from the
- mother. In dominant disorders a single copy of the disease gene (received
- from either the mother or father) will be expressed "dominating" the other
- normal gene and resulting in appearance of the disease. The risk of
- transmitting the disorder from affected parent to offspring is fifty percent
- for each pregnancy regardless of the sex of the resulting child.
-
- Affected Population
-
- Chromosome 11/14 Translocation is a rare disorder associated with certain
- types of leukemia. There are many types of leukemia, some of which are not
- rare.
-
- Related Disorders
-
- Leukemias are the generalized cancerous (neoplastic) disorders of the blood
- forming tissue, such as bone marrow. They primarily affect tissues forming
- the white blood cells (leukocytes), causing an abnormally high accumulation
- of white blood cells. There are many different types of Leukemias. (For
- more information on these disorders, choose "leukemia" as your search term in
- the Rare Disease Database).
-
- Hodgkin's Disease is a form of cancer of the lymphatic system, especially
- the lymph nodes. Tumors occur in the lymph nodes and/or the area around the
- nodes. Fever, night sweats, and weight loss may occur along with the swollen
- lymph nodes. (For more information on this disorder, choose "Hodgkin's" as
- your search term in the Rare Disease Database).
-
- Letterer-Siwe Disease (Histiocytosis-X) is a hereditary disorder
- characterized by generalized enlargement of lymph nodes, liver and spleen,
- combined with persistent low-grade fever. Symptoms include pallor,
- yellowish-brown spotty elevated (maculopapular) lesions, sometimes with
- ulceration. (For more information on this disorder, choose "Histiocytosis-X"
- as your search term in the Rare Disease Database).
-
- Myelofibrosis-Osteosclerosis is a disorder characterized by the growth of
- fibrous tissue in the bone marrow causing anemia, weakness and fatigue due to
- constant replacement of normal bone marrow cells. Episodes of severe pain in
- the abdomen, bones and joints may also occur. (For more information on this
- disorder, choose "Myelofibrosis" as your search term in the Rare Disease
- Database).
-
- Therapies: Standard
-
- Treatment of leukemia associated with Chromosome 11/14 Translocation may
- include the following:
-
- Chemotherapy involves the use of "anticancer" drugs. Leukeran
- (chlorambucil) is one drug that is often used for standard treatment of
- leukemia. Radiotherapy (radiation) may be used to destroy lymphocytes and
- shrink enlarged lymph nodes. Prednisone, an immunosuppressive drug, may also
- be used. Other treatment is symptomatic and supportive.
-
- Therapies: Investigational
-
- Leukapheresis is a procedure by which leukocytes are removed from the
- patient's blood. Pentaspan is an orphan drug which has recently been
- approved for marketing, and is used to aid in leukapheresis.
-
- There are several orphan drugs being used on an experimental basis or in
- clinical trials to treat different types of leukemia.
-
- For Acute Lymphocytic Leukemia (ALL), the following orphan drugs are
- being tested:
-
- erwinia l-asparaginase by Porton Products, Ltd., Encino, CA, and also by
- LyphoMed, Inc., Melrose Park, IL.
- PEG-L-asparaginase by Enzon, Inc., South Plainfield, NJ.
-
- For B-cell Leukemia, orphan drugs being tested are the following:
-
- ImmuRAIT, LL-2-I-131 by Immunomedics, Inc., Warren, NJ.
- ST1-RTA Immunotoxin (SR 44163) by Sanofi, Inc., New York, NY.
-
- For Chronic Lymphocytic Leukemia, the orphan drug being tested is:
-
- fludarabine phosphate by Triton Biosciences, Alameda, CA.
-
- For treatment of primary immunodeficiency disease associated with T-cell
- defects, there is recombinant Interleukin-2 being developed by Cetus Corp.,
- Emeryville, CA.
