Trisomy 15q23----qter due to a de novo t(11;15)(q25;q23) and assignment of the critical segment.
A 10 10/12-year-old boy with a de novo t(11;15)(q25;q23) leading to trisomy 15q23----qter was studied. The clinical features were compatible with other cases of distal trisomy 15q. The critical segment for this trisomy is tentatively assigned to bands 15q25----qter.
