Genes…… (2/2)

Most of the genes are the elements of fibers ¾ slender bundle of protein provide strength and flexibility to connective tissue throughout the body. Elastic fibers allow the skin to stretch ¾ the lungs to expand & contract and arteries to handle the pressure of blood flow.

The major component of elastic fibers ¾ Elastin ¾ is produced from ELN gene. Other critical proteins of elastic fibers are produced by the following genes:


Mutations in any of these gene hamper the formation, assembly or function of elastic fibers.

Now, a shortfall in elastic fibers weakens connective tissue in the skin, arteries, lungs and other organs. These mutations in connective tissue cause the major feature of ‘Cutis Laxa’ to a small percentage. Researcher suspects that mutation in other genes, which is yet to identify may also be responsible for Cutis Laxa.

The chances of Acquired Cutis Laxa (ACL) are very rare. Acquired Cutis Laxa (ACL) is caused by the destruction of normal elastic fibers and not by inheritance. Though the causes of ACL are unclear, but it may occur due to the side effect any medical treatment which remove copper from body.

Cutis Laxa is caused by the mutation in the following genes:

Inheritance .....

Most of the cases Cutis Laxa is inherited. There generally 3 types of forms of genetic inheritance…

E Sex Linked
E Autosomal Dominant
E Autosomal Recessive

The Autosomal Recessive form is the most common & severe.

The defective/mutated gene is carried on one of the sex chromosomes, in this case it is located on the X chromosome
Autosomal Dominant
Only one copy of the defective/mutated gene is enough to cause CL. A child has a 50% chance of inheriting the gene from either parent.
Autosomal Recessive
In this type the affected child must inherit two copies of the defective/mutated gene from both of its parent. The chance of transmitting an autosomal recessive disease is 25% for each pregnancy.

History .....

Historically, Cutis Laxa (CL) was often confused with EDS (Ehlers Danlos syndrome), until 1923, when E. Parkes Weber noted the clinical differences between these two condition.

The internal involvement and the systemic nature of CL were elucidated by Goltz and co-workers, who emphasized the phenomenon of generalized elastolysis in same patient.

Prevalence .....

The prevalence of ‘Cutis Laxa’ is estimated 1 in every 1,000,000 birth.

Cutis Laxa is extremely rare. As per National Institute of Health, only around 200 families are suffering from this disorder, worldwide.

The Name .....

The term ‘Cutis Laxa’ is a Latin word which means ‘Loose/Lax Skin

Cutis Laxa is all about ……

In a one liner Cutis Laxa is a rare inherited connective tissue disorder, characterized by inelastic saggy skin, with droopy appearance.

Connective tissue is the body’s supporting framework of tissue consisting of strands of collagen, elastic fibers between muscles and around muscle groups, blood vessels and simple cells. Connective tissue provides stricture and strength to the muscles, joints, organs and skin.

Meet the Little Yuxin ..... (2/2)

The little, Yuxin Xiaoli was born with a loosening skin. Her tiny face is full of wrinkles. The skin on her cheeks and chins drooped. She had even more sagging skin in other parts of her body.
