Individuals WDR26-related Intellectual Disability syndrome or Skraban-Deardorff Syndrome (SKDEAS) have all been reported to have delays in walking and/or talking, differences in the way they walk, and specific facial features that are unique. Other common features include low muscle tone, occasional differences in the structure of the brain, and behavioural differences such as autism.
SKDEAS is rare and occurs in approximately 1 in 1500 children with developmental delay, or an estimated 1 in 25,000 children.
