| Abstract: | A 46-year-old man with mental retardation, growth failure and some dysmorphic features is found to have a 46,XX,r(3)(p26q29) karyotype in 93% of his peripheral lymphocytes. This observation is compared with previously cases of ring 3. The existence of a "ring syndrome" is considered. |
