Ring chromosome 20 is a rare chromosomal abnormality characterized mainly by refractory epileptic seizures, cognitive and behavioral problems, and absence of definite dysmorphic features. We report a 5-year-old boy with refractory epilepsy and minimal dysmorphic features who first presented with mild developmental delay at 11 months of age. The karyotype of the child was 46,XY,r(20)(p13q13.3). Till date there are 69 cases of ring chromosome 20 reported in the literature, including mosaics and supernumerary ring chromosomes. To our knowledge, this is the first case of ring chromosome 20 with refractory epilepsy reported from the south Indian population.
