HFE基因突变命名为C282 Y(g.5474G→A; GenBank登录号Z92910),通常通过Feder等(1)描述的引物在PCR中扩增基因组DNA,然后基于Sna B1(2)或Rsa 1(3)切割位点的产生进行限制性酶切来检测。据报道,位于反义引物结合位点3′端5个核苷酸内的多态性(5569 G/A)导致C282 Y纯合性的假阳性结果(4)。在分析具有5569 G/A多态性的C282 Y杂合子复合体时,由于含有C282 Y的等位基因的选择性扩增而出现假阳性结果。设计了一条新的不与5569 G/A位点结合的反义引物(5′-TACCTCCTCAGGCACTCCTC-3′)。
The HFE gene mutation designated C282Y (g.5474G→A; GenBank accession no. Z92910) is usually detected by the primers described by Feder et al. (1) in a PCR to amplify genomic DNA followed by restriction enzyme cleavage based on the production of either a Sna B1 (2) or a Rsa 1 (3) cut site. A polymorphism (5569G/A) located five nucleotides within the 3′ end of the binding site for the antisense primer has been reported to lead to false-positive results for C282Y homozygosity (4). The false-positive result occurs in analysis of a C282Y heterozygote compound with the 5569G/A polymorphism because of selective amplification of the C282Y-containing allele. A new antisense primer (5′-TACCTCCTCAGGCACTCCTC-3′) that did not bind the 5569G/A site was designed (4 …
