Genetic diseases are caused by changes to the DNA in genes. These changes are often inherited from one parent to the next. Sometimes these changes happen spontaneously, showing up for the first time in an unaffected child. This process is called a new mutation, and it can lead to mistakes in the instructions for certain proteins. This can lead to proteins that do not work properly or can not be made at all, resulting in genetic disorders.
Fragile X syndrome
Fragile X syndrome is a hereditary disease, with widespread effects on the body. Those with the disorder are likely to have a wide range of physical, mental, and emotional problems, as well as a short lifespan. For women with the condition, early menopause is a common symptom, while older carriers may suffer from tremors and balance problems. There are also many behavioral and emotional problems associated with the condition. Children who are born with this disorder often exhibit behavior similar to that of autistic children.
Fragile X syndrome is caused by an alteration in the FMR1 gene, which produces a protein that helps the brain function. The gene is changed, making it unable to produce the normal FMRP protein. The disorder is inherited in an ‘X-linked’ way, with men more affected than women. Men with the condition have only one X chromosome, while women have two X chromosomes.
Symptoms of fragile X syndrome are not immediately obvious. In babies, there are no obvious signs. The biggest symptom is a disproportionately large head circumference. However, an experienced geneticist can detect subtle differences in facial characteristics, as well as intellectual disability. If the condition is not diagnosed in time, the disease will often progress into other problems, such as mental retardation and autism.
While there is no known cure, the CDC is committed to improving the quality of life for those with this condition. CDC works with family members to provide support and information for individuals with the disorder. The organization also works with the Fragile X community to improve the quality of life for those affected.
Genetic testing for Fragile X syndrome is not routinely done on babies. However, it is recommended for children who have developmental problems. Usually, a blood sample is collected and sent to a laboratory to determine the mutation in the FMR1 gene.
Fragile X syndrome affects 1 in 3,600 girls and boys. However, the number of carriers is much higher: around one in one hundred and eighty men and women are carriers. Pre-mutation carriers may have no symptoms, but may pass on the altered FMR1 gene to their children.
Fragile X syndrome is a condition caused by a mutation in the FMR1 gene, which is necessary for normal brain development. People with the disorder may experience social and behavioral difficulties and may have difficulty paying attention. They may also exhibit signs of autism.
Haemochromatosis
Haemochromatosis is an inherited condition that results in an excess accumulation of iron in the body. It causes organ damage and deterioration of tissues. This disease is mainly affected in men. However, women may also experience the symptoms. A person suffering from haemochromatosis should take special care to reduce the amount of iron in their body.
Symptoms of hemochromatosis vary among individuals but the common characteristics are the same in men and women. Common symptoms include arthritis of the hands and ankles, chronic fatigue, decreased sex drive, and increased glucose levels. Some patients may also develop bronze or gray skin colour. This condition is also associated with increased chances of developing heart disease.
The Canadian Hemochromatosis Society provides educational and support programs for people affected by this disease. The Society also organizes information sessions, community events, and other resources. The Society is currently celebrating its 40th anniversary with a cross-country bus tour that will engage with people with the disease, raise awareness about this condition, and support families affected by it.
Haemochromatosis is also associated with the presence of two inherited mutant genes in the body. This mutation causes the disease. It is common in people with northern European ancestry. The disease affects about one in every 300 people.
Haemochromatosis is caused by the presence of certain mutations in the HFE gene. This disease is hereditary and is passed from parent to child. Most patients have two mutated copies of this gene, though not all people with two mutated copies will develop symptoms.
Haemochromatosis is an inherited disorder that causes an excessive amount of iron to be absorbed by the body. This excess iron is stored in organs such as the liver and pancreas. This excess iron can damage tissues. If left untreated, the condition can be fatal.
Treatment for haemochromatosis involves removing excess iron from the body. Because most of the iron in the body is stored in red blood cells, regular removal of blood can reduce the amount of excess iron in the body. Phlebotomy is a safe, simple procedure that may need to be repeated weekly for as long as two years. The patient should also limit their intake of alcohol because alcohol can stress the liver.
Huntington’s disease
Huntington’s disease is a genetic disorder that is inherited as an autosomal dominant trait. This means that one copy of the disease gene will prevail over a normal gene, resulting in the appearance of the disease. There is a 50% chance that a person will pass the disorder to their children. This risk is the same regardless of sex or pregnancy.
The symptoms of Huntington’s disease vary depending on the stage of the disease. The juvenile form of the disease is present in approximately 10% of all people and has a much faster course. Juvenile Huntington disease is often difficult to diagnose, because the symptoms are quite different than the adult version. For instance, chorea is usually less prominent in juvenile Huntington disease. A team of professionals is needed to diagnose the condition.
Huntington’s disease is caused by the degeneration of nerve cells, or neurons, in certain brain regions. These areas include the basal ganglia, which regulates movement, and the cerebral cortex, which is the outer region of the brain and is involved in conscious thought. Huntington’s disease is most commonly diagnosed in people aged thirty to fifty, and its symptoms progress slowly over time. Juvenile Huntington’s disease usually results in death within ten years of onset.
Huntington’s disease is a progressive neurological disorder that results in uncontrolled muscle movements. The disease also causes personality changes and affects memory. In a few cases, the disease may progress to the point where the person will be bedridden. A person with this disease has difficulty thinking or talking.
Adults can develop the disease at any age. Early signs may include irritability, depression, or small involuntary movements. Other symptoms include difficulty learning and making decisions. While a person with HD may be able to live with the symptoms of the disease, it is important to note that there is currently no cure for this condition.
Huntington’s disease can disrupt relationships and social activities. It affects facial, tongue, and throat muscles, which may cause a person to not initiate conversations or engage in social activities. People with the disease may be unable to initiate conversations, but their understanding of what people want and need is usually unaffected.
Huntington disease (HD) is caused by a mutation in the huntingtin gene. The disease can be passed from generation to generation and is a fatal disease. There is no known cure, and HD is progressive. However, early symptoms are easier to deal with. Symptoms of HD can include moodiness, clumsiness, and small uncontrolled movements. In severe cases, it may cause a person to have difficulty in performing daily activities.
