A NEW ISOLATED 20q INTERSTITIAL DUPLICATION CASE AND ITS CLINICAL COMPARISON WITH SIMILAR ISOLATED CASES.

Duplications of 20q are rare. Here we report a 15 years old boy with de novo duplication of 17.1 Mb at chromosome 20q. We made a comparison with the other isolated 20q duplication cases. There are phenotypic similarities between the patients who have the same affected chromosomal regions. We also showed a clinical follow up of the patient. There may be a relationship with Glaucoma and Graves disease between the chromosomal region and these diseases may occur at the other patients when they get older.
