Ring chromosome 15 in child with a minor dysmorphism of phenotype.
The analysis of a karyotype of a girl with slight mental retardation, without significant dysmorphism, showed the presence of a ring chromosome in group 13-15. By the application of G technique it was discovered that in this case it was an aberrant chromosome 15. Besides retardation in growth and a slight mental backwardness in this case, it was confirmed that in cases of ring 15 syndrome no preponderant change appears in phenotype.
