Partial trisomy 14q -- and parental translocation of No. 14 chromosome. Report of a case and review of the literature.

A case of partial trisomy 14 (47, + 14q-) is presented. The proband's mother had a balanced translocation of 14q with the long arm of a No. 3 chromosome. Clinical and cytogenetic findings of this case are compared with 5 other cases of 47, + 14q-, in which one parent had a balanced translocation of the distal part of the No. 14 long arm to another chromosome. It appears that this chromosomal aneuploidy produces a fairly typical clinical picture.
