Analysis of the CAG repeat locus among 28 unrelated clinically diagnosed HD patients from the eastern part of India showed that the range of expansion of CAG repeats was between 41 and 56 in the huntingtin gene. The smallest size of the CAG repeat which causes HD is not defined precisely. In Western ...

ABSTRACT: We tested the hypothesis that two well-characterised functional polymorphisms of the microsomal epoxide hydrolase gene (EPHX1), T113C and A139G, may influence susceptibility to chronic obstructive pulmonary disease (COPD) and asthma. We genotyped participants from the Copenhagen City Heart ...
