Jan 6, 2018 · Autism spectrum disorder has no single known cause. Given the complexity of the disorder, and the fact that symptoms and severity vary, there are probably many causes. Both genetics and environment may play a role.
Jan 25, 2024 · Key points. Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. People with ASD often have problems with social communication and interaction, and restricted or repetitive behaviors or interests. People with ASD may also have different ways of learning, moving, or paying attention.

Aug 20, 2019 · FIGURE 1. Genetic modifiers in autism spectrum disorder. Autism is estimated to be 40–80% heritable. However, both genetic and non-genetic factors modulate the penetrance of risk genes, resulting in a highly heterogeneous disease phenotype for similar pathogenic variants.
- Williams Syndrome. Williams Syndrome (also known as Williams-Beuren syndrome) is a rare genetics disorder in which a portion of DNA material on chromosome 7 is missing.
- Fragile X. Fragile X syndrome (also known as Martin-Bell syndrome) is a sex-linked genetic disorder. The exact frequency of Fragile X syndrome is unclear, but the CDC estimates that roughly 1.4 in 10,000 males and 0.9 in 10,000 females are affected by this disorder.
- Landau-Kleffner Syndrome. Landau-Kleffner Syndrome is a rare form of epilepsy that manifests as a form of aphasia, (loss of language), which usually develops between 3 and 7 years.
- Prader-Willi Syndrome. Prader-Willi Syndrome is a disorder which is sometimes associated with, but not a subtype of, autism.
