View Missing Chromosome 15 Autism Images. In some cases, chromosome 15, distal trisomy 15q may be characterized by abnormally slow growth before and/or after birth (prenatal and/or postnatal growth retardation). There are two types of 15q duplications linked to autism — an interstitial duplication within the chromosome, and an isodicentric form, in which a duplication of based on the figures, the dup15q alliance aims to reach out to this untapped population and encourage them to participate in research.

People who possess a specific change in one of their chromosomes are nearly 14 times more likely to develop an autism spectrum disorder or the change, which is called a deletion, happens when a section of chromosome 17 is missing. The deletion is found only in people who have an autism. Chromosome 15q duplication is a chromosome abnormality that occurs when an extra (duplicate) copy of the genetic material located on the long arm (q) of chromosome 15 is present in each cell.
People who have this microdeletion may experience a range of symptoms including learning difficulties, developmental delay, and behavioral problems.
Autism spectrum disorders are highly heterogeneous and include both idiopathic and syndromic forms. There are many different genetic pathways into autism, and they are not specific to one chromosome.
