Learn About Wiedemann-Rautenstrauch Syndrome

What is the definition of Wiedemann-Rautenstrauch Syndrome?

Wiedemann-Rautenstrauch syndrome is a type of progeria, which is a group of genetic conditions characterized by the dramatic, rapid appearance of aging earlier in life than expected. Signs and symptoms of Wiedemann-Rautenstrauch syndrome begin before birth. Affected individuals do not grow and gain weight at the expected rate before and after birth. People with this condition have distinctive facial features that give the appearance of old age. They often have a large head, a triangular face with a prominent forehead and pointed chin, a small mouth with a thin upper lip, low-set ears, and abnormal lower eyelids. In most affected individuals, the middle of the face looks as though it has been drawn inward (midface retraction). On the head, hair is sparse and the veins stand out. Also contributing to the appearance of aging is a lack of fatty tissue under the skin (lipodystrophy), particularly in the face, arms, and legs. In addition, the skin is thin and translucent. Some affected individuals develop joint abnormalities called contractures that can limit movement.

What are the causes of Wiedemann-Rautenstrauch Syndrome?

Wiedemann-Rautenstrauch syndrome is caused by mutations in a gene called POLR3A. This gene provides instructions for making the largest piece (subunit) of an enzyme called RNA polymerase III. This enzyme is involved in the production (synthesis) of ribonucleic acid (RNA), a chemical cousin of DNA. RNA polymerase III helps synthesize several forms of RNA, including those that assemble protein building blocks (amino acids) into working proteins. This process is essential for the normal functioning and survival of cells in tissues throughout the body.

How prevalent is Wiedemann-Rautenstrauch Syndrome?

Wiedemann-Rautenstrauch syndrome is a rare disorder. Its prevalence is unknown.

Is Wiedemann-Rautenstrauch Syndrome an inherited disorder?

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
