People with a family history of the disorder who want to have a child should talk to a doctor specializing in genetics. [3] About 90% of cases occur due to a new mutation during early development, while 10% are inherited. The deletion of genes from chromosome 22 usually occurs as a random event in the fathers sperm or in the mothers egg, or it may occur early during fetal development. Approximately 90% of patients with the clinical diagnosis of DGS have a small deletion of a specific portion of chromosome number 22 at position 22q11.2, called a microdeletion.
