YAC clones for the creatine kinase, mitochondrial 2 (sarcomeric; CKMT2), gene were isolated. One of these YACs was localized on chromosome 5q13.3 by fluorescence in situ hybridization. A polymorphic dinucleotide repeat (heterozygosity 0.77) was identified within the seventh intron of the CKMT2 gene. Genotyping of CEPH families allowed positioning of CKMT2 on the multipoint map of chromosome 5 between D5S424 and D5S428, distal to spinal muscular atrophy (SMA) (5q12-q14).
分离出了肌酸激酶线粒体2(肌节;CKMT2)基因的酵母人工染色体(YAC)克隆。其中一个YAC通过荧光原位杂交定位在5号染色体q13.3上。在CKMT2基因的第七个内含子内鉴定出一个多态性二核苷酸重复序列(杂合度为0.77)。对CEPH家系进行基因分型,从而将CKMT2定位在5号染色体的多点图谱上,位于D5S424和D5S428之间,在脊髓性肌萎缩症(SMA)(5q12 - q14)的远端。
