Gene mutations were detected in 25 patients and a 18-year-old girl among 16 families. Trinucleotide repeats of CAG were 73~79. The fragments of abnormal alleles were 380~402bp, and all patients were heterozygous. The copy numbers of normal alleles were 18~40, fragments from 202~270bp. SCV reduction was much obvious compared to MCV, MCV and SCV in lower limb ?ere much more slow than that in upper's. BAEP, VEP were also delayed in latency. The anticipation in parental sex bias were much more obvioius than that in matental's. Cerebellar ataxia was most severe, the next were dysarthria and bulging eyes. Amytrophy was seen only in bed ridden patients. Cerebellar atrophy was more severe than brain stem, cord atrophy was n't observed in all MJD.
结果检出10个家系25例病人及1例症状前18岁女孩有MJD基因突变,CAG三核苷酸重复73~79次,异常等位基因片段长380~402bp,均为杂合子;正常人CAG三核苷酸重复18~40次,等位片段长200~270bp,电生理发现MJD的SCV减慢比MCV明显,而下肢的MCV、SCV又较上肢明显,BAEP、VEP均有不同程度的潜伏期延长或波的异常;MJD的父亲遗传早于母亲,进展也较块,临床以小脑性共济失调为突出症状,其次为构音障碍、突眼等,肌肉萎缩仅见于晚期病人;MRI示小脑萎缩较明显,脑干萎缩并不严重,未见明显的颈髓萎缩。

There were three isozyme (AMY1, AMY2 and AMY3) at the locus of amylase in Qinghai Merino, moreover, there were two genotypes of AMY2A and AMY2O at the AMY2. Monomorphism was tested at the locus of AMY in Gansu Alpine Merino. The degree of genetic variability estimated by Nei's expected average heterozygosity for the 6 blood protein loci was relatively higher in Gansu Alpine Merino and in Qinghai Merino than that in others, which indicated that there are higher genetic variations and richer genetic diversity in Alpine Merino.
从6个血液蛋白位点的Nei氏预期平均基因杂合度所估计的群体内的遗传变异以及与本研究其它群体的结果相比来看,甘肃高山细毛羊和青海细毛羊的群体内的遗传变异相对较大,而其它群体内的遗传变异则相对较小,说明高原型细毛羊群体内遗传变异程度较大,遗传多样性较丰富,具有较大的选择潜力,为高原型细毛羊进一步选育提高提供了遗传基础。

The results were as follows: Firstly, the S-locus of Katy was heterozygous, and self-compatibility was dominant to self-incompatibility. Secondly, a very extensive segregation in self-pollinated fruiting rate, fertile flower rate and average fruit weight was observed in the F1 populations, and averages of these traits were lower than that of mid-parent means. Therefore, these traits were confirmed to be quantitative.
