Most studies focus on autism or autism spectrum disorders, rather than Asperger's Syndrome specifically. More than one chromosome is linked to autism spectrum disorders. The chromosomes involved according to various studies are listed below.
A few sites providing information on the genetics of autism highlight results about several of the chromosomes:

What else can I help you with?
What chromosome is polycystic kidney disease found?
It is a mutated gene called PKD1 located on chromosome 16.
What chromosome number is affected in Lowe syndrome?
Lowe syndrome is caused by a mutated gene on the X sex chromosome. Because it is X-linked, it occurs almost exclusively in males.
On which chromosome is the defective gene located in Hurler's syndrome?
The defective gene in Hurler syndrome is located on chromosome 4. This gene carries instructions for making an enzyme called alpha-L-iduronidase, which is essential for breaking down certain complex molecules in the body. When this gene is mutated, the enzyme is deficient, leading to the accumulation of harmful substances in the cells.
What kind of gene pair is found in the female carrier of a sex linked disorder?
In the female carrier of a sex-linked disorder, there would typically be one normal allele and one mutated allele for the gene associated with the disorder on the X chromosome. This is because females have two X chromosomes, and one copy of the X chromosome with the mutated allele can be masked by the normal allele on the other X chromosome.
Is fragile x syndrome sex linked?
Yes. It is found as a mutation on the X chromosome (a sex chromosome) so it is sex linked. The gene for Fragile X is carried on the X chromosome. Because both males (XY) and females (XX) have at least one X chromosome, both can pass on the mutated gene to their children.
Is hunters disease dominant or recessive?
Hunter's disease is inherited in an X-linked recessive pattern. This means the mutated gene that causes the disease is located on the X chromosome, and males are more commonly affected because they only have one X chromosome. Females can carry the mutated gene but are typically unaffected due to having a second X chromosome that can compensate.
Why are female carriers?
Females carry two X chromosomes; males only carry one. A female carrier carries a defective recessive allele for a gene on the X chromosome. Thus, the female will not be affected because she still has a copy of the dominant allele. However, if she has any male children, that child will be affected because males inherit their X chromosome from their mothers.
What is Inherited on a sex chromosome that can cause human genetic disorder such as color blindness and hemphilia?
Inherited on a sex chromosome, genetic disorders such as color blindness and hemophilia are caused by mutations in specific genes located on the X chromosome. These disorders are more commonly seen in males because they have only one X chromosome, making them more likely to express recessive X-linked traits. Females, with two X chromosomes, are typically carriers of the mutated gene but may not exhibit the disorder unless they inherit two copies of the mutated gene.
What various types of genetic material in order from simplest to most complex?
nucleus → chromosome → gene
Is autism caused by a dominant gene?
yes , autism is caused by a dominant gene
Why does Duchenne muscular dystrophy affect boys?
Duchenne muscular dystrophy is inherited as an X-linked recessive genetic disorder, meaning the gene mutation that causes the condition is located on the X chromosome. Since boys have only one X chromosome inherited from their mother, they are more likely to develop Duchenne muscular dystrophy if they inherit the mutated gene. Girls have two X chromosomes, so even if they inherit one mutated gene, they often have a second normal X chromosome that can compensate for the mutation.
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
