Early symptoms include cramping, twitching, or stiffness of the muscles; slurred nasal speech; difficulty swallowing or chewing, and muscle weakness in an arm or leg. The disorder is determined by genes on the X chromosome. Charcot-Marie-Tooth disease (CMT) 11. Unlike Down syndrome, however, Tay-Sachs results from a defect found in chromosome #15, and the disorder is irreversibly fatal when found in children. Common Down syndrome symptoms are: Single gene inheritance is also called Mendelian or monogenetic inheritance. Currently there is no direct proof that taking folic acid and B vitamins lower homocysteine levels and prevent heart attacks and strokes. This gene provides instructions for the production of red blood cells. This extra chromosome results in small stature and low muscle tone, among other…, Sickle cell disease is an inherited condition that can have life threatening consequences. It also causes problems with how the pancreas works and with how food is absorbed. Down syndrome occurs when a person receives an extra copy of chromosome 21. For example, different genes that influence breast cancer susceptibility have been found on chromosomes 6, 11, 13, 14, 15, 17, and 22. Carrier screening. Most cases occur for the first time within the person who has the disorder. Giving birth to a child with a genetic condition can be concerning for parents, but effective ongoing care from trained nursing professionals can significantly ease the impact. There are thousands of known single gene inheritance diseases, and they may be inherited in different ways. Last medically reviewed on September 14, 2020, DNA is perhaps the most famous molecule on earth. However, modern medicine has produced methods of identifying the potential health outcomes of genetic disorders, as evidenced by medical research from educated, advanced-degreed nurse practitioners and practicing physicians. MedicineNet does not provide medical advice, diagnosis or treatment. List of Examples of Common Single-Inheritance Genetic Diseases, List of Examples of Multifactorial Genetic Inheritance Disorders, List of Examples of Chromosome Abnormalities Genetic Diseases, List of Examples of Mitochondrial Genetic Inheritance Disorders, Genetic (Hereditary) Diseases: Types and List Examples Topic Guide, Read more about the early warning signs and symptoms of Alzheimer's disease, Multifactorial genetic inheritance disorders, Mitochondrial genetic inheritance disorders. The 46 human chromosomes (22 pairs of autosomal chromosomes and 2 sex chromosomes) between them house almost 3 billion base pairs of DNA that contains about 20,500 protein-coding genes. This coiled structure is called a chromosome. Since genes pass from parent to child, these disorders may be heritable. [11] In contrast, one in every 16,300 Hispanic-American babies is diagnosed with the disease. COVID Most Contagious Soon After Infection, Normal Blood Sugar Levels (Ranges) In Adults with Diabetes, upward slanting eyes, ears are flat and positioned The coding regions make up less than 5% of the genome (the function of all the remaining DNA is not clear) and some chromosomes have a higher density of genes than others. People with homocystinuria die at an early age. Examples of these genetic disorders include heart disease, Alzheimer's disease, and heart disease. The lists have examples of genetic disease types and are not all inclusive. However, the following treatments may help a person manage them: Genetic disorders occur as a result of a mutation to DNA. Genes are located on chromosomes, which are stick-shaped structures in the middle of the cell (nucleus) . Some common chronic diseases are multifactorial disorders. See additional information. There are a variety of liver diseases caused by liver inflammation, scarring of the liver, infection of the liver, gallstones, cancer, toxins, genetic diseases, and blood flow problems. However, some develop within a person for the first time. Abnormalities in an individual's genetic makeup cause genetic disease. The way a gene is inherited can help determine the risk of it in a current or future pregnancy. Down syndrome is a lifelong condition. There is currently no way to stop or slow the progression of Huntington’s disease. Most cells within the body contain the molecule DNA. Therefore, a person has two copies of every gene. 8. This is when a chromosome segment rearranges from one location to another. There are other causes of hyperhomocysteinemia, for example, alcoholism. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the disabilities to be created within the child. This mutation may affect whole chromosomes or the specific genes within chromosomes. What is dementia? This causes the cells to clump together and become caught in blood vessels, triggering severe pain and serious complications such as infections, organ damage, and acute respiratory syndrome. Cystic Fibrosis is a chronic, genetic condition that causes patients to produce thick and sticky mucus, inhibiting their respiratory, digestive, and reproductive systems. The disease attacks the nerve cells responsible for the control of voluntary muscles. This condition inhibits oxygen flow throughout the body. Most genetic diseases are the direct result of a mutation in one gene. Examples of chromosome abnormality disorders include: Mitochondrial genetic inheritance disorders are caused by mutations in the DNA of mitochondria, small particles within cells. The risk of having a baby with a birth defect from a genetic change increases if: The parents have another child with a genetic disorder. There are about 6000 known genetic disorders; many are fatal or cause severe problems while others may not but may add to problems that are triggered by non-genetic (for example, environmental conditions). home/genetic disease center /genetic disease article. This molecule provides the cell with instructions on how to function. Males are mainly affected and have the disorder. What degree program are you most interested in? These DNA mutations result in the mitochondria failing to produce enough energy to sustain the body’s cells. This is when a person has 2 or more sets of chromosomes in his or her cells with different genetic material. For example, Down syndrome (sometimes referred to as "Down's syndrome") or trisomy 21 is a common genetic disorder that occurs when a person has three copies of chromosome 21. There are several different genetic disorders. View all blog posts under Articles | View all blog posts under Doctor of Nursing Practice |. Amniocentesis. Genetic disorders can be inherited, or passed from parents to offspring, or acquired due to changes in an individual’s DNA that occur during their lifetime. Down syndrome is a chromosomal disorder.

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Examples include: Achondroplasia. Mitochondrial genetic inheritance disorders. This means that each cell within the body contains three copies of chromosome 21 instead of the usual two copies. Some symptoms of liver disease include jaundice, nausea and vomiting, easy bruising, bleeding excessively, fatigue, weakness, weight loss, shortness of breath, leg swelling, impotence, and confusion. Scientists are now able to test adults and unborn babies for alleles that can cause genetic disorders.
