Brief report: a case of chromosome 22 alteration associated with autistic syndrome.

Doctors looked at one 13-year-old boy who had autism. They checked his chromosomes and found a rare ring shape on chromosome 22.

The report simply describes the boy and the genetic finding. No therapy or test results are given.

The ring chromosome 22 was present alongside autistic behaviors. The authors say this match is worth noting.

They urge teams to order genetic karyotyping when autism is diagnosed.

Vollmer et al. (1996) saw the same ring 22 in a young adult, but that patient showed bipolar mood swings, not autism. Same chromosome, different outcome — so ring 22 can lead to more than one profile.

Konstantareas et al. (1999) screened 127 autistic children and found several chromosomal changes. Their larger set shows the ring 22 case is part of a small, mixed group.

Green et al. (1986) first reported autosomal defects in four autistic clients, paving the way for later single-case notes like this one.

If you work with autistic clients who also have intellectual delay or unusual facial features, ask the pediatrician about a karyotype. Spotting a chromosomal cause won’t change your ABA plan, but it alerts the family to possible medical risks tied to that chromosome. You can also use the finding to explain why skills may progress on a different timeline.
