โฆ Synopsis
We present a patient with multiple anomalies and severe developmental delay. A small supernumerary ring chromosome was found in 40% of her lymphocyte cells at birth. The origin of the marker chromosome could not be determined by GTG banding, but fluorescent in situ hybridization (FISH) later identified the marker as deriving from chromosome 17. Am. J. Med. Genet. 69:352-355, 1997.

We report on a 3-year-old-girl with mosaic partial trisomy 17 due to an additional ring chromosome 17 in 13% of cells analysed. This was identified by fluorescence in situ hybridisation (FISH) using a whole chromosome 17 specific paint as well as probes specific for the Smith-Magenis and Miller-Diek
Initial approaches to prenatal diagnosis from fetal karyotyping involved application of standard cytogenetic techniques. However, when fetal samples, such as chorionic villus cells or amniocytes are used, small chromosome rearrangements cannot be easily identified because they lack a distinct bandin
