Terminal deletion 4q in a severely retarded boy.
We report a boy with a de novo terminal deletion of chromosome 4q, (q31----qter) and compare him to 17 previously reported cases with the same anomaly. This case contributes further to the delineation of the del(4)(q31) phenotype, which seems to be clinically recognizable.
