Neurofibromatosis-Noonan syndrome

A variant of neurofibromatosis type 1 characterised by the combination of features of neurofibromatosis type 1, such as café-au-lait spots, iris Lisch nodules, axillary and inguinal freckling, optic nerve glioma and multiple neurofibromas; and Noonan syndrome, with features such as short stature, typical facial features, congenital heart defects and unusual pectus deformity. [from SNOMEDCT_US]

Neurofibromas

Neurofibromatosis is a genetic disorder of the nervous system. It mainly affects how nerve cells form and grow. It causes tumors to grow on nerves. You can get neurofibromatosis from your parents, or it can happen because of a mutation (change) in your genes. Once you have it, you can pass it along to your children. Usually the tumors are benign, but sometimes they can become cancerous. There are three types of neurofibromatosis: . -Type 1 (NF1) causes skin changes and deformed bones. It usually starts in childhood. Sometimes the symptoms are present at birth. -Type 2 (NF2) causes hearing loss, ringing in the ears, and poor balance. Symptoms often start in the teen years. -Schwannomatosis causes intense pain. It is the rarest type. Doctors diagnose the different types based on the symptoms. Genetic testing is also used to diagnose NF1 and NF2. There is no cure. Treatment can help control symptoms. Depending on the type of disease and how serious it is, treatment may include surgery to remove tumors, radiation therapy, and medicines.

Neurofibromatosis, type 1

Neurofibromatosis 1 (NF1) is characterized by multiple café-au-lait spots, axillary and inguinal freckling, multiple cutaneous neurofibromas, and iris Lisch nodules. Learning disabilities are present in at least 50% of individuals with NF1. Less common but potentially more serious manifestations include plexiform neurofibromas, optic nerve and other central nervous system gliomas, malignant peripheral nerve sheath tumors, scoliosis, tibial dysplasia, and vasculopathy. [from GeneReviews]

Cystic fibrosis

Cystic fibrosis (CF) is a multisystem disease affecting epithelia of the respiratory tract, exocrine pancreas, intestine, hepatobiliary system, and exocrine sweat glands. Morbidities include progressive obstructive lung disease with bronchiectasis, frequent hospitalizations for pulmonary disease, pancreatic insufficiency and malnutrition, recurrent sinusitis and bronchitis, and male infertility. Pulmonary disease is the major cause of morbidity and mortality in CF. Meconium ileus occurs at birth in 15%-20% of newborns with CF. More than 95% of males with CF are infertile. Congenital absence of the vas deferens (CAVD) is generally identified during evaluation of infertility or as an incidental finding at the time of a surgical procedure. Hypoplasia or aplasia of the vas deferens and seminal vesicles may occur either bilaterally or unilaterally. Testicular development and function and spermatogenesis are usually normal. [from GeneReviews]

Peripheral neuropathy

Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body. . There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders. Symptoms often start gradually, and then get worse. They include . - Numbness. - Pain. - Burning or tingling. - Muscle weakness. - Sensitivity to touch. Treatment aims to treat any underlying problem, reduce pain and control symptoms. NIH: National Institute of Neurological Disorders and Stroke.  [from MedlinePlus]

Hereditary cancer-predisposing syndrome

The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance. [from MeSH]

Neuromuscular Diseases

Neuromuscular disorders affect the nerves that control your voluntary muscles. Voluntary muscles are the ones you can control, like in your arms and legs. Your nerve cells, also called neurons, send the messages that control these muscles. When the neurons become unhealthy or die, communication between your nervous system and muscles breaks down. As a result, your muscles weaken and waste away. The weakness can lead to twitching, cramps, aches and pains, and joint and movement problems. Sometimes it also affects heart function and your ability to breathe. Examples of neuromuscular disorders include. -Amyotrophic lateral sclerosis. -Multiple sclerosis. -Myasthenia gravis. -Spinal muscular atrophy. Many neuromuscular diseases are genetic, which means they run in families or there is a mutation in your genes. Sometimes, an immune system disorder can cause them. Most of them have no cure. The goal of treatment is to improve symptoms, increase mobility and lengthen life.  [from MedlinePlus]
