Abstract :
A new case of ring chromosome 9 in a 36-month-old child is presented. In addition to the pathognomonic features of this rare disorder (only 21 cases reported), our patient presents some peculiarities, such as corpus callosum hypoplasia and epileptic seizures (infantile periodic spasms). We also observed a reduced level of leukocyte interferon α whose synthesis is controlled by a gene on chromosome 9 and which could be responsible for the recurrent respiratory tract infections, typical and sometimes fatal in these patients.
