Skraban-Deardorff syndrome (SKDEAS)

What is Skraban-Deardorff syndrome?

It is a rare neurodevelopment syndrome. Intellectual disability and developmental delay are characteristic of the syndrome. Seizures and distinct facial features are also associated with the syndrome.

It is also referred to as WDR26-related intellectual disability.

This syndrome is also known as:
Intellectual Disability with Seizures, Abnormal Gait, and Distinctive Facial Features

What gene changes cause Skraban-Deardorff syndrome?

Mutations in the WDR26 gene are responsible for causing the syndrome.

It is inherited in an autosomal dominant pattern.

What are the main symptoms of Skraban-Deardorff syndrome?

Developmental delay and intellectual disability are the main features of the syndrome. The extent of the delay may vary in its severity between affected individuals, and range from mild to severe. However, all individuals experience speech delay with many never learning to speak. A few affected individuals begin to speak in their second year of life.

In some instances, individuals have also been diagnosed with autism-like features, including specific behaviors that include rocking and abnormal hand movements.

Seizures are a common symptom, but most if not all of the seizures that occur are treatable.

How is Skraban-Deardorff syndrome diagnosed?

To find out if someone has a diagnosis of Skraban-Derdorff syndrome, it is important to have a consultation and evaluation with a clinical genetic specialist.  Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis.  FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.

Yunis-Varon syndrome (YVS)

It is a rare genetic disease that affects multiple systems of the body. Its main symptoms affect the skeletal and nervous systems, as well as ectodermal tissue (hair and teeth). Since 1980 just 25 cases from 19 families have been diagnosed and recorded. This syndrome is also known as: Cleidocranial Dysplasia With Micrognathia, Absent Thumbs, And Distal Aphalangia

Xia-Gibbs syndrome (XIGIS)

It is a rare genetic syndrome associated mainly with intellectual disability. This syndrome is also known as: Mental Retardation, Autosomal Dominant 25; Mrd25 Changes in the AHDC1 gene are responsible for causing the syndrome. It is inherited in an autosomal dominant pattern, although all cases of the syndrome recorded so far have been the result of de novo or new mutations in the gene. In the case of autosomal dominant inheritance just one parent is the carrier of the gene mutation, and they have a 50% chance of passing it onto each of their children. Syndromes inherited in an autosomal dominant inheritance are caused by just one copy of the gene mutation. In some cases, a genetic syndrome may be the result of a de-novo mutation and the first case in a family. In this case, this is a new gene mutation which occurs during the reproductive process.
