What are the symptoms of marble bone disease?

Fractures are frequent; deafness and loss of vision may occur because cranial nerves become compressed by the narrowing of their passageways as bone is deposited in the skull. Severe cases may be fatal, but individuals with mild cases of the disorder may have a normal life expectancy.

Can marble bone disease be prevented?

Complications of osteopetrosis can be reversed or prevented in early life by bone marrow transplantation. Clinical studies have shown that regular administration of interferon-gamma-1b can significantly slow the progression of the disease and reduce infection rates, with few serious side effects.

What gene causes marble bone disease?

Osteopetrosis is caused by underlying mutations that interfere with the acidification of the osteoclast resorption pit, for example due to a deficiency of the carbonic anhydrase enzyme encoded by the CA2 gene.

Is osteopetrosis curable?

For people with autosomal recessive osteopetrosis, the most severe form, allogenic hematopoietic stem cell transplantation (HSCT) can cure the condition. Most signs and symptoms (bone sclerosis, bone marrow failure, and extramedullary hematopoiesis) can be prevented or reversed by HSCT.

Who gets marble bone disease?

Osteopetrosis (literally “stone bone,” also known as marble bone disease or Albers-Schonberg disease) is an extremely rare inherited disorder where the bones harden and become denser. The disorder can cause osteosclerosis. The estimated prevalence of osteopetrosis is 1 in 100,000 to 500,000.

Who is affected by marble bone disease?

The adult type of osteopetrosis affects about 1,250 individuals in the United States. The incidence is about one in every 20,000 individuals. Males and females are affected in equal numbers. The X-linked form of osteopetrosis affects predominantly males due to the mode of inheritance of the mutation.

Is osteopetrosis serious?

As a result, people with severe osteopetrosis are at risk of abnormal bleeding, a shortage of red blood cells (anemia ), and recurrent infections. In the most severe cases, these bone marrow abnormalities can be life-threatening in infancy or early childhood.

What is the treatment for marble bone disease?

Treatment. The only durable cure for the form of osteopetrosis that affects the osteoclasts (which is more common) is a bone marrow transplant [3]. If complications occur in children, patients can be treated with vitamin D. Interferon-gamma has also been shown to be effective, and it can be associated with vitamin D.

Is osteopetrosis a disease or disorder?

Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked.

Why is osteoporosis bad?

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.

What organs are affected by osteoporosis?

Osteoporotic bone breaks are most likely to occur in the hip, spine or wrist, but other bones can break too. In addition to causing permanent pain, osteoporosis causes some patients to lose height. When osteoporosis affects vertebrae, or the bones of the spine, it often leads to a stooped or hunched posture.

How serious is osteomyelitis?

Osteomyelitis is a serious condition and if it is left untreated, the infection can advance to other joints and other parts of the body. This will lead to widespread infection and septic and even bone death by affecting the blood circulation within the bone.

What are some rare skeletal diseases?

Another rare bone disease is called Paget’s disease and itinvolves the growth of bones which are simply too large and too weak for theirown size. Other rare bone diseases include primary hyperparathyroidism and XLH.

What causes osteoporosis disease?

Osteoporosis Diseases. Type I osteoporosis is caused by hormonal changes while Type II is caused by dietary deficiencies. Osteoporosis can also be caused by major surgery, corticosteroid drugs (anti-inflammatory drugs), liver cirrhosis , Crohn ‘s inflammatory disease of the bowel, cystic fibrosis , and hormone deficiencies.

What causes osteoporosis Quizlet?

The leading cause of osteoporosis is a lack of certain hormones , particularly estrogen in women and androgen in men. Women, especially those older than 60 years of age, are frequently diagnosed with the disease. Menopause is accompanied by lower estrogen levels and increases a woman’s risk for osteoporosis.
