This gene provides instructions for producing a protein that regulates the activity of other genes. Within the developing brain, the ARX protein is involved with movement (migration) and communication of nerve cells (neurons). In particular, this protein regulates genes that play a role in the migration of specialized neurons (interneurons) to their proper location. Interneurons relay signals between other neurons.</p><p>The normal ARX protein contains four regions where a protein building block (amino acid) called alanine is repeated multiple times. These stretches of alanines are known as polyalanine tracts. The most common mutation that causes Partington syndrome, a duplication of genetic material written as c.428_451dup, adds extra alanines to the second polyalanine tract in the ARX protein. This type of mutation is called a polyalanine repeat expansion. The expansion likely impairs ARX protein function and may disrupt normal interneuron migration in the developing brain, leading to the intellectual disability and dystonia characteristic of Partington syndrome.</p><p class=\"section-source\"><a href=\"https://medlineplus.gov/genetics/condition/partington-syndrome/#causes\">MedlinePlus Genetics: Causes</a></p>","key":"forms","title":"What causes Partington syndrome?"},{"bodyHtml":"<p>The intellectual disability associated with Partington syndrome usually ranges from mild to moderate. Some affected individuals have characteristics of autism spectrum disorders that affect communication and social interaction. Recurrent seizures (epilepsy) may also occur in Partington syndrome.</p><p>Focal dystonia of the hands is a feature that distinguishes Partington syndrome from other intellectual disability syndromes. Dystonias are a group of movement problems characterized by involuntary, sustained muscle contractions; tremors; and other uncontrolled movements. The term &quot;focal&quot; refers to a type of dystonia that affects a single part of the body, in this case the hands. In Partington syndrome, focal dystonia of the hands, which is called the Partington sign, begins in early childhood and gradually gets worse. This condition typically causes difficulty with grasping movements or using a pen or pencil.</p><p>People with Partington syndrome may also have dystonia affecting other parts of the body; dystonia affecting the muscles in the face and those involved in speech may cause impaired speech (dysarthria). People with this disorder may also have an awkward way of walking (gait).
