<unk> , also known as<unk>  deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome. It also has neurocognitive effects, and has been implicated as a genetic factor for autism and schizophrenia.<unk>  is not to be confused with<unk>  microduplication syndrome, caused by the addition of genetic material in the same region from which it is removed in the<unk> , or<unk> 1.31<unk>  syndrome, another name for Koolen–De Vries syndrome.
