What is Apert syndrome?

Apert syndrome is

a rare genetic condition that is apparent at birth

. People with Apert syndrome can have distinctive malformations of the skull, face, hands, and feet. Apert syndrome is characterized by craniosynostosis, a condition in which the fibrous joints (sutures) between bones of the skull close prematurely.

autosomal recessive single-gene diseases

often show a clear pattern in which the disease “skips” one or more generations. Phenylketonuria (PKU) is a prominent example of a single-gene disease with an autosomal recessive inheritance pattern.

Are all diseases genetic?

Researchers are learning that

nearly all conditions and diseases have a genetic component

. Some disorders, such as sickle cell disease and cystic fibrosis, are caused by variants (also known as mutations) in single genes. The causes of many other disorders, however, are much more complex.
