The presence of the apolipoprotein E4 allele (apoE4) has been recognized as a risk factor for the development of presenile and senile forms of Alzheimer's dementia (AD).
The apoE alleles frequency of 71 normal controls (NC), 60 demented controls (DC) and 50 senile type AD subjects was determined by polymerase chain reaction in order to get data about the apoE polymorphism of the Hungarian AD population.
The apoE3/3 genotype was the most common in all groups. The apoE4 frequency was significantly higher (28%) in the AD group than that was (7% and 9%) in the NC and DC populations, respectively. No apoE4 homozygotes were found in the DC group and the number of heterozygotes was lower in the DC than in the AD group.
The results are in good agreement with others in the literature and support the occurrence of an increased apoE4 allele frequency in Hungarian senile AD population.
载脂蛋白E4等位基因(apoE4)的存在已被公认为是早老性和老年性阿尔茨海默病(AD)发生的一个风险因素。
为获取匈牙利AD人群载脂蛋白E多态性的数据,采用聚合酶链反应测定了71名正常对照(NC)、60名痴呆对照(DC)和50名老年性AD患者的载脂蛋白E等位基因频率。
apoE3/3基因型在所有组中最为常见。AD组中apoE4频率(28%)显著高于NC组(7%)和DC组(9%)。DC组未发现apoE4纯合子,且DC组杂合子数量低于AD组。
结果与文献中的其他研究结果高度一致,并支持匈牙利老年性AD人群中apoE4等位基因频率增加的现象。
