- Autosomal dominant is a pattern of inheritance characteristic of some genetic disorders. “Autosomal” means that the gene in question is located on one of the numbered, or non-sex, chromosomes. “Dominant” means that a single copy of the mutated gene (from one parent) is enough to cause the disorder.

Autosomal dominant traits pass from one parent onto their child. Autosomal recessive traits pass from both parents onto their child. Autosomal refers to the 22 numbered chromosomes as opposed to the sex chromosomes (X and Y).

How do I inherit traits?
Traits are passed from the sperm and egg. Genetic material consists of: DNA. Genes. Chromosomes. Chromosomes are made up of DNA, and chunks of that DNA form genes. That DNA holds your genetic code. You receive one copy of a gene from each parent, creating a pair. Those genes are in your cells, which divide and copy themselves until your body has enough cells to make up all of your body. When the cells divide, the chromosomes and genes should stay the same in each cell of the same line. Sometimes during division there's a mistake in the division of genetic material. That's called a mutation. It may change the function of the cell it's in. Advertisement
How do inherited traits affect my body?
Inherited traits determine your physical characteristics, including how you look and what makes you unique. Sometimes, you can inherit genes that have altered DNA (genetic mutation) that form as a result of a copying mistake during cell division. Mutations may lead to genetic conditions that affect how your cells form and function, but they don’t always. Some genes can mutate and not cause disease, and some can cause serious illness if they mutate.
Where is DNA in my body?
DNA lives in every cell in your body — generally in the nucleus, which is the control center of the cell. Trillions of cells make up who you are.
What does DNA look like?
Your DNA is made of four bases: adenine (A), cytosine (C), thymine (T) and guanine (G). The bases form pairs (base pairs): A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (forming a nucleotide) that create a spiral staircase (double helix). The base pairs form the steps and the sugar and phosphate molecules are the rails.
How does a mutation change my DNA?
A genetic mutation can happen during cell division or if the cell is exposed to something toxic. A mutation is a change in DNA’s double helix structure. This means that a gene isn't where it's supposed to be on a chromosome. Mutations can be caused by: Substitution: One nucleotide switches place with another nucleotide. Insertion: An extra nucleotide is added to a strand of DNA. Deletion: A nucleotide is removed from a strand of DNA.
What are common genetic disorders caused by autosomal dominant inheritance?
Genetic disorders that follow a pattern of autosomal dominant inheritance include: Huntington’s disease. Marfan syndrome. Achondroplasia.
What are common genetic disorders caused by autosomal recessive inheritance?
Genetic disorders that follow a pattern of autosomal recessive inheritance include: Cystic fibrosis. Sickle cell disease. Tay-Sachs disease.
Is there a test to check the health of my genes?
There are multiple ways to test for genetic problems. A genetic test identifies changes to your genes, chromosomes or proteins. Genetic testing can locate mutated genes that cause genetic conditions. These tests help parents who plan on having children understand their risk of passing a genetic condition to their child.
How do I prevent genetic disorders from passing to my children?
It's not possible to determine which genes to pass on to children, so it isn’t possible to prevent genetic conditions from passing to your children. To better understand your risk of passing a specific genetic condition that runs in your family, talk with your healthcare provider about genetic testing and speak with a genetic counselor who can walk you through the test results.

Oct 27, 2020 · Autosomal dominant or dominance is a pattern of genetic inheritance that occurs within an autosome (non-sex chromosome). The way we look and function is most commonly the result of dominance of one parental gene over the other.
Single gene disorders that affect a gene on one of the 22 autosomal chromosome pairs are called autosomal disorders. Disorders that affect the sex chromosome are called X-linked disorders. Disorders are further described according to whether the affected genetic change is dominant or recessive.
Sep 17, 2024 · X-linked dominant disorders are caused by mutations in genes on the X (female) chromosome. Females have two X chromosomes and will have the disorder if either of the X chromosomes carries the mutation.

Do mutated genes cause autosomal dominant disorders?
Dominant traits are expressed when even one copy of the gene for that trait is present. Recessive traits carried on autosomal chromosomes can be expressed only when two copies of the gene for that trait are present, one on each of the pair of chromosomes.
