What genetic disorders are X-linked?

Some X-linked conditions that individuals may be familiar with are Fragile X syndrome, hemophilia A, and Duchenne muscular dystrophy. But there are some conditions that are more common in females, such as Rett syndrome, which is also due to mutation on the X chromosome.

What disease is caused by a gene on the X chromosome?

Diseases such as hemophilia and Duchenne muscular dystrophy occur from a recessive gene on the X chromosome.

What are the most common X-linked disorders?

The most common X-linked recessive disorders are:

• Red–green color blindness, a very common trait in humans and frequently used to explain X-linked disorders.
• Hemophilia A, a blood clotting disorder caused by a mutation of the Factor VIII gene and leading to a deficiency of Factor VIII.

Are there any X-linked dominant disorders?

Examples of X-linked dominant disorders include Rett syndrome, the X-linked lissencephaly and double-cortex syndrome, and incontinentia pigmenti type 1, characterized by dermatological, ocular, dental, and neurological abnormalities.

What are some Y linked disorders?

Hypertrichosis of the ears, webbed toes, and porcupine man are examples of Y-linked inheritance in humans. Hypertrichosis of the ears (or hairy ears) is a condition wherein there is a conspicuous growth of hair on the outside rim of the ear.

What does genetic diseases, X-linked mean?

If the gene is on one of the first 22 pairs of chromosomes, called the autosomes, the genetic disorder is called an autosomal condition. If the gene is on the X chromosome, the disorder is called X-linked. Genetic disorders also are grouped by how they run in families.

What are the top 10 genetic disorders?

Here is a list of the top 10 genetic disorders which are most common and prevalent world wide: Familial combined hyperlipidemia Familial hypercholesterolemia Dominant otosclerosis Adult polycystic kidney disease Multiple exostoses Huntington ’s disease Fragile X-syndrome Neurofibromatosis Cystic fibrosis Duchenne muscular dystrophy

What does X linked disorders mean?

Incontinentia pigmenti is X-linked disorder affecting Skin, Hair, Teeth and Central Nervous System. Choroideremia is an X-linked disorder, which means that it is caused by a faulty gene, called CHM, on the X chromosome. (7) However, two of the best-described forms of Kallman syndrome are inherited autosomal dominant and X-linked disorder.

What are X linked traits?

X-linked traits are sex-linked traits determined by genes on the X-chromosome. Some X-linked traits in humans are; red-green colorblindness, Duchenne muscular dystrophy , hemophilia A , and hemophilia B . These are all recessive traits, and affect males with a much greater frequency than females.
