Trisomy 9p in a patient with a de novo 9/15 translocation

Mental retardation, facial dysmorphism, hypertelorism, antimongoloid eye slants, epicanthus, globular nose, malformed ears, bone abnormalities, one flexion crease on 5th finger, simian crease, and speech difficulties with delayed expressivity were found in a girl with trisomy of the short arm of chromosome 9. The 9p+ syndrome was due to a sporadic translocation of the short arm of chromosome 9 onto the short arm of chromosome 15.
