17q12 Deletion Syndrome
17q12 deletion syndrome is a chromosome abnormality in which there is a small missing piece (deletion) of genetic material on the long arm (q) of chromosome 17. Signs and symptoms can vary widely among people with this syndrome. More common signs and symptoms include abnormalities of the kidneys or urinary tract, a form of diabetes called maturity-onset diabetes of the young type 5 (MODY5), and mildly distinctive facial features. Other signs and symptoms may include developmental delay, intellectual disability, and behavioral or psychiatric disorders. Some people with 17q12 deletion syndrome have seizures, and/or abnormalities of the eyes, liver, brain, genitalia, or other body systems.
17q12 deletion syndrome is inherited in an autosomal dominant manner; however, in most people with this syndrome, the deletion is not inherited from a parent and occurs sporadically. Less commonly, a person with 17q12 deletion syndrome inherits the deletion from a parent. Children of a person with the deletion have a 50% chance of inheriting the deletion.
Treatment depends on the specific signs and symptoms in each person. Even in the absence of structural abnormalities of the kidneys, they should continue to be monitored for problems that may arise.
