[Ring of the chromosome 4. II. Without facial dysmorphism]
Annales De Genetique
|June 1, 1977
Abstract:
A r(4) was observed in a 5-year-old female patient, with growth retardation, a near normal psychomotor development and with no major dysmorphism. The break points were in p16 and q33. After comparison with other known observations of r(4) it is suggested that the phenotype of monosomy 4p is due to monosomy for the distal band 4p16.
