Results (1) The prevalence of CBS 844 ins 68 and MS A2756G in the subjects of this study were somewhat lower than that of Western Caucasian populations. There was no siganificant differcences in the frequences of CBS844ins68, MS A7756G and MTHFR C677T mutations between the patient groups and control proup.

结果 1。本研究中CBS844ins68和MS A2756G的基因突变率较国外所报道者低；CBS 844ins 68、MS A2756G和MTHFR C677T的各种基因型频率在病人组与正常对照组之间的差异无显著性；正常对照组CBS844ins 68杂合突变率较病人组有升高趋势。2。

Methods Four probands from four unrelated families with typical manifestations of CADASIL were studied The 1～12 coding exons and their flanking intron sequences of NOTCH3 gene were amplified by PCR and sequenced Some family members in the pedigree 2 and 4 were also examined for the NOTCH3 gene mutations Results Four hete...
