【摘要】 用HPLC法测定新疆蒙古族78例、锡伯族60例新生儿胎儿血红蛋白（HbF）中Gγ／Aγ以及AγI／AγI比值。％Gγ均值为：蒙古族73.99％，锡伯族74.59％。％GγI均值分别为蒙古族56.04％和锡伯族64.33％。在蒙古族中发现AγT纯合体4例、杂合作12例；锡伯族中发现AγT杂合体6例。蒙古族中AγT基因频率（ρAγT）为0.128，锡伯族为0.05更多还原

【Abstract】 Gγ / Aγ, AγI/AγT Ratios of fetal hemoglobin (HbF) in 138 cases of newborns of Mognol(n= 78) and Sibo (n = 60) ethnic groups in Urumuqi, Xinjiang were determined by HPLC. The means of%Gγ of Mongol and Sibo ethnic groups were 73.99% and 74.59% respcctively. 12 AγT cases ofheterozygotes in Mongol, 6 in Sibo and 4 cases of AγI homozygotes in Mongol were found. The frcquen-cies of AγT gcne were 0.128 in Mongol and 0.05 in Sibo respectively. The means of AγT of Mongol andSibo ethnic groups were 56.04% and 64.33% respectively.更多还原
