What does ABCA12 do?

What does ABCA12 do?

Normal Function The ABCA12 gene provides instructions for making a protein known as an ATP-binding cassette (ABC) transporter. ABC transporter proteins carry many types of molecules across cell membranes.

Where is the ABCA12 gene?

The ABCA12 gene is active in some types of skin cells and in several other tissues, such as testis, placenta, lung, stomach, and fetal brain and liver. This protein appears to be essential for normal development of the skin, which provides a barrier between the body and its surrounding environment.

Which of the following is the disease that develops as a result of ABCA12 gene mutation?

Harlequin Ichthyosis is a severe skin disease caused by mutations in the human gene encoding ABCA12.

What chromosome is ABCA12 on?

ABCA12: Harlequin type of congenital ichthyosis The ABCA12 gene located on chromosome 2q34 encodes a keratinocyte lipid transporter protein. The transporter plays an important role in transporting lipids in cells that make up the outermost layer of the skin (Yamanaka et al., 2007).

What causes lamellar ichthyosis?

Although the condition may be caused by changes ( mutations ) in one of several different genes , approximately 90% of cases are caused by mutations in the TGM1 gene. Lamellar ichthyosis is generally inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.

Which chromosome is the ABCA12 gene in?

What causes Harlequin ichthyosis?

Mutations in the ABCA12 gene cause harlequin ichthyosis. The ABCA12 gene provides instructions for making a protein that is essential for the normal development of skin cells. This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis).

Is there a cure for lamellar ichthyosis?

Unfortunately, there is currently no cure for lamellar ichthyosis. Management is generally supportive and based on the signs and symptoms present in each person. For infants, providing a moist environment in an isolette (incubator) and preventing infection are most important.

Is there a cure for Harlequin syndrome?

There’s no cure for Harlequin ichthyosis, so management becomes a crucial part of the equation after initial treatment. And it’s all about the skin. Skin protects the body from bacteria, viruses, and other harmful elements in the environment. It also helps to regulate body temperature and fluid loss.

What is the function of the ABCA12 gene?

ATP-binding cassette sub-family A member 12 also known as ATP-binding cassette transporter 12 is a protein that in humans is encoded by the ABCA12 gene. ABCA12 belongs to a group of genes called the ATP-binding cassette family, which makes proteins that transport molecules across cell membranes.

Where is ABCA12 located in the human body?

ABCA12. The ABCA12 gene is active in some types of skin cells and in several other tissues, such as testis, placenta, lung, stomach, and fetal brain and liver. This protein appears to be essential for normal development of the skin, which provides a barrier between the body and its surrounding environment.

What kind of skin disorder does ABCA12 cause?

Mutations in the ABCA12 gene also cause another severe skin disorder, lamellar ichthyosis type 2. People with this disorder have red, scaly, plate-like skin covering most of their bodies.

What makes up the chain of an antibody?

Antibodies exist as one or more copies of a Y-shaped unit, composed of four polypeptide chains. Each Y contains two identical copies of a heavy chain, and two identical copies of a light chain, which are different in their sequence and length.
