PG - 405-10 AB - Clinical and molecular cytogenetic studies in a case with partial trisomy 12p due to a de novo supernumerary ring chromosome: We report on a girl with a mosaic karyotype containing a supernumerary ring chromosome. Fluorescence in situ hybridization (FISH) studies showed that this marker chromosome was derived from chromosome 12, resulting in partial trisomy 12p13.1-->12q11. The girl showed developmental delay, cerebral visual impairment, obesity and mild dysmorphic features. Her clinical data at 6 months, 3 years, and 6 years of age were compared with the clinical data on other trisomy 12p patients.
