Proud syndrome

What causes Proud syndrome?

Proud syndrome is caused by changes (mutations) in the ARX gene, which encodes a protein that regulates the activity of other genes. This protein is especially important during early embryonic development since it is thought to be involved in the formation of many different body structures such as the pancreas, testes, brain, and muscles used for movement (skeletal muscles). For example, the protein helps regulate the process by which cells mature to carry out specific functions (differentiation) within the pancreas, testes, and muscles. In the developing brain, it plays many different roles such as assisting with the movement of neurons to their final locations. Specific changes in the ARX gene impair the function of the protein, which may disrupt the normal development of many different parts of the body. This can lead to the many signs and symptoms associated with Proud syndrome.

How is Proud syndrome inherited?

Proud syndrome is inherited in an X-linked recessive manner. A condition is considered X-linked if the mutated gene that causes the condition is located on the X chromosome, one of the two sex chromosomes (the Y chromosome is the other sex chromosome). Women have two X chromosomes and men have an X and a Y chromosome.

In X-linked recessive conditions, men develop the condition if they inherit one gene mutation (they have only one X chromosome). Females are generally only affected if they have two gene mutations (they have two X chromosomes), although some females may rarely have a mild form of the condition if they only inherit one mutation. A woman with an X-linked recessive condition will pass the mutation on to all of her sons and daughters. This means that all of her sons will have the condition and all of her daughters will be carriers. A man with an X-linked recessive condition will pass the mutation to all of his daughters (carriers) and none of his sons.

How might Proud syndrome be treated?

The treatment of Proud syndrome is based on the signs and symptoms present in each person. For example, spasticity may be treated with a variety of therapies including medications and/or physical therapy. Medications may be prescribed to help prevent and/or control recurrent seizures. Surgery may be required to treat certain physical abnormalities such as kidney or genital issues. Children with severe intellectual disability may benefit from special education services.
