Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.
Angelman syndrome
A rare syndrome causing physical and intellectual disability. It can't be cured, but some therapies can improve the quality of life of those affected....
Given this more restrictive definition, the only genetic disorders that we currently cure are those that can be managed surgically (e.g., the correction of cleft palate, the repair of a congenital heart defect, or colectomy for familial polyposis of the colon).
The prognosis of a genetic condition includes its likely course, duration, and outcome. When health professionals refer to the prognosis of a disease, they may also mean the chance of recovery; however, most genetic conditions are life-long and are managed rather than cured.
In the future, genetic therapies may be used to prevent, treat, or cure certain inherited disorders, such as cystic fibrosis, alpha-1 antitrypsin deficiency, hemophilia, beta thalassemia, and sickle cell disease.
Although promising, most genetic therapies are still under development and have a long way to go before their efficacy and safety can be proved. The uncertainty surrounding this topic therefore means the success of genetic therapies in treating or curing rare genetic diseases is not yet assured.
We may soon see cures for rare diseases like sickle cell disease, muscular dystrophy and progeria, a rare and progressive genetic disorder that causes children to age rapidly. Further into the future, gene therapies may help treat more common conditions, like heart disease and chronic pain.
Cystic fibrosis (CF) is the most common, fatal genetic disease in the United States.
Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Genetic disorders and congenital anomalies are considered the leading cause of infant mortality in the United States, 1 , 2 based on data from the National Center for Health Statistics (NCHS) at the Centers for Disease Control and Prevention.
Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that ...
Every person is born with mutations. Most of these mutations will not cause disease on their own, but it is important to identify any that do. Depending on which gene is affected, single gene disorders can be passed down even when the mother and father do not show any symptoms.
Around 1 in 50 people are affected by a known single-gene disorder, while around 1 in 263 are affected by a chromosomal disorder. Around 65% of people have some kind of health problem as a result of congenital genetic mutations.
Scientists have long recognized that many psychiatric disorders tend to run in families, suggesting potential genetic roots. Such disorders include autism, attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depression and schizophrenia.
One of the most highly genetically inherited psychiatric disorders is bipolar disorder which may affect as much as 1-4% of the population. Bipolar disorder is characterized by periods of depression followed by periods of abnormally elevated mood (mania/hypomania).
Risk Factors for Genetic Disorders
One parent has a chromosomal abnormality. Advanced maternal age (35 or older) Advanced paternal age (40 or older) Multiple miscarriages or prior stillbirth.
Cancer. Cancer refers to the uncontrolled growth of abnormal cells in the body. This can affect almost any organ or tissue including lungs, breast, colon, skin and ovaries. Due to the complexity of the disease and the variety of forms it can take, developing a cure has proven difficult.
“We generally say: Several thousand diseases affect humans of which only about 500 have any U.S. Food and Drug Administration-approved treatment,” said Cindy McConnell, a spokeswoman at NIH's National Center for Advancing Translational Sciences (NCATS).
The three leading causes of burden of disease in 2030 are projected to include HIV/AIDS, unipolar depressive disorders, and ischaemic heart disease in the baseline and pessimistic scenarios.
A girl born with a rare and deadly genetic condition is expected to live a long and normal life after becoming the first person to be cured on the NHS with the help of a revolutionary gene therapy.
