What does genetic disorder mean?
A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence.

What is the definition of a genetic disorder?
Can a genetic disorder affect any gene or chromosome?
However, not everyone with a genetic condition in their family will experience symptoms of the disorder. Genetic conditions can affect any gene or chromosome. This means that there are a wide range of genetic disorders, each causing various symptoms. What is the human genome?
How are genetic disorders passed down from generation to generation?
Genetic disorder. In other genetic disorders, defects may be caused by new mutations or changes to the DNA. In such cases, the defect will only be passed down if it occurs in the germline . Some types of recessive gene disorders confer an advantage in certain environments when only one copy of the gene is present.
Can a genetic disorder be inherited from a parent?
Such mutations are not inherited from a parent, but occur either randomly or due to some environmental exposure (such as cigarette smoke). These include many cancers, as well as some forms of neurofibromatosis. A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence.
What are some facts about genetic disorders?
A genetic disorder is a disorder that results from an abnormality in a person’s genome. The abnormality can be something very tiny to very major. Some genetic disorders are the result of acquired mutations or changes in a preexisting group of genes or single gene, while other disorders are inherited by an individual’s parents.
What are some examples of genetic disorders?
Examples of these genetic disorders include heart disease, Alzheimer’s disease, and heart disease. In addition, chronic diseases such diabetes, cancer and arthritis are examples of this type of disorder. Multifactorial inheritance disorders are also associated with inherited traits such as height, skin color, and eye color.
What causes genetic disorder?
Causes for genetic disorders. Genetic disorders are caused by changes in the structure or number of the chromosomes or in the DNA. Genetic problems arise due to different reasons: DNA and GENES: The DNA, is a unique, spiral- shaped molecule found in all living cells.
How many diseases are genetic?
A genetic disease is due to a faulty gene or group of genes. While not all gene defects cause disease, many do. New genetic diseases are discovered every month; as of 2001, there are estimated to be approximately 1,100 genetic diseases.
