Abstract
An r(4) [ring-4 chromosome] was observed in a 5 yr old female patient, with growth retardation, a near normal psychomotor development and with no major dysmorphism. The break points were in p16 and q33. Compared with other known observations of r(4), the phenotype of monosomy 4p might be due to monosomy for the distal band 4p16.
