Chromosome 18

It was so scary to learn that our child had a rare genetic disorder and the hospital didn’t have information to give us. Then to have the doctors give you worst case scenarios and not much hope. I’m so glad that I didn’t listen and I did my own research. The Chromosome 18 Registry & Research Society has been able to lead me in the necessary directions I needed to go. Finding answers to my questions of why my son was delayed in speech, why he had poor muscle tone, vision and hearing impairments, why he has such severe learning difficulties and feeding issues. I learned that each of our children “have complex medical and educational needs. And each child’s condition is dependent upon their syndrome. Some will, with appropriate therapies and treatment for their medical concerns, be able to live on their own or in a group setting. Others may spend a lifetime gaining basic self-help skills to function on a daily basis.”

The Science of Chromosome 18: Chromosome 18 is estimated to contain approximately 400 genes. Chromosome abnormalities involve the deletion or duplication of hundreds of genes.


Trisomy 18: There are three copies instead of the usual two.

Tetrasomy 18p: An extra chromosome is present, which is made up of 2 copies of the short arm.

18 p-: There is a missing piece from the short arm of chromosome 18.

18 q-: There is a missing piece from the long arm of chromosome 18.

Ring 18: One of the copies of chromosome 18 forms a ring, and material is lost from both the long and short arms.
