Overview[edit | edit source]
The exact cause of Asperger (AS) is unknown. Many factors including genetics, family history of autism spectrum disorders (ASD) and enviornmental factors such as older parental age, prematurity, low birth weight and pregnancy complications have been associated with autism spectrum disorder (ASD).[1][2][3][4][5][6][7]
Causes[edit | edit source]
Genetic Causes[edit | edit source]
- Linkage at 1q21-22[1]
- Linkage at 13q31-33[1]
- Linkage at 3p14–24[1]
- Linkage at 3q21–24[6]
- 17p breakpoints in t(13;17) and t(17;19)[5]
- 3p22.1p21.31 microdeletion[8]
Family History of Autism Spectrum Disorder (ASD)[edit | edit source]
Several studies suggest that a familial history of autism spectrum disorder (ASD) is a risk factor for Asperger Syndrome (AS).[4][3][2]
Environmental Factors[edit | edit source]
Several environmental risk factors are associated with autism spectrum disorder (ASD) which include:[7]
- Advanced maternal age
- Advanced paternal age
- Low birth weight
- Prematurity
- Hyperbilirubinemia, neonatal jaundice
- Maternal immigrant status
- Pregnancy complications such as eclampsia and pregnancy-induced hypertension
- Air pollutants (traffic-related)
