Abstract

A balanced maternal chromosome translocation (9p24;21q214) resulted in two offspring with unbalanced karyotypes. One of these, a girl trisomic for both segment 9pter to 9p24 and segment 21pter to 21q214, was found to have a SOD-A activity not significantly different from those found in a group of five cases with trisomy 21. However, clinical evaluation of this girl revealed no symptoms of the Down syndrome. These findings suggest that, providing the gene dosage theory is correct, the gene for SOD-A is probably localized on chromosome 21 proximal to, or in, band q21.

摘要

一次平衡的母源染色体易位(9p24;21q214)导致了两个核型不平衡的后代。其中一个是女孩,9号染色体短臂末端至9p24以及21号染色体短臂末端至21q214均三体,发现其超氧化物歧化酶A(SOD-A)活性与一组5例21三体病例中的活性无显著差异。然而,对该女孩的临床评估未发现唐氏综合征的症状。这些发现表明,如果基因剂量理论正确,SOD-A基因可能定位于21号染色体q21带近端或其上。
