To evaluate the use of multiple displacement amplification (MDA) for preimplantation genetic diagnosis (PGD) of α- and β-double thalassemia.
Whole genome of a single cell was directly amplified using MDA and its products were used as templates in fluorescent gap polymerase chain reaction (PCR) analysis of α-thalassemia and in PCR-reverse dot blot analysis, singleplex fluorescent PCR of β-28 and CD17 mutation and HumTH01 for β-thalassemia.
The use of MDA as a universal step allows for the simultaneous diagnosis of two or more hereditary defects.
评估多重置换扩增(MDA)在α-和β-双重地中海贫血症的植入前遗传学诊断(PGD)中的应用。
使用 MDA 直接扩增单细胞的全基因组,并用其产物作为荧光 gap 聚合酶链反应(PCR)分析α-地中海贫血和 PCR-反向点杂交分析、β-28 和 CD17 突变和β-地中海贫血的 HumTH01 的模板。
1)单细胞的 MDA 可以产生足够的 DNA 模板,用于检测α和β-地中海贫血;2)成功地将建立的 MDA-PGD 方案应用于 6 个胚胎的 PGD 中,其中 3 个进行了转移,但没有妊娠。
MDA 的使用作为一个通用步骤,可以同时诊断两种或更多种遗传性缺陷。
