Genetic linkage has been analyzed between cystic fibrosis (CF) and a number of markers on the long arm of chromosome 7, including D7S15, COL1A2, PON, MET, D7S8, and TCRB, using a cohort of 47 Canadian and 13 Danish CF families. The analysis confirms the previous observations that both MET and D7S8 are closely linked to CF. Based on the result from one family, MET appears to be more proximal to the centromere than CF. Our analysis also suggests that genetic heterogeneity may account for the high recombination fraction between CF and D7S8 observed in another family. In addition, a strong linkage disequilibrium has been observed between CF and the two closely flanking markers.
利用47个加拿大囊性纤维化(CF)家庭和13个丹麦CF家庭组成的队列,对CF与7号染色体长臂上的多个标记(包括D7S15、COL1A2、PON、MET、D7S8和TCRB)之间的遗传连锁进行了分析。该分析证实了之前的观察结果,即MET和D7S8均与CF紧密连锁。根据一个家庭的结果,MET似乎比CF更靠近着丝粒。我们的分析还表明,遗传异质性可能是另一个家庭中观察到的CF与D7S8之间高重组率的原因。此外,在CF与两个紧密侧翼标记之间观察到了强烈的连锁不平衡。
