The results showed that no significant correlation existed between this RFLP locus and NIDDM. Marked differences were found, however, between the genotype distribution of low LDL level subgroups of NIDDM patients and normal controls. It was inferred that the H1 allele might be associated with high blood cholesterol levels, and the H2 allele with low cholesterol levels. Disturbances of lipid metabolism occur frequently in diabetes mellitus. This study suggested that differences in LDLR genotypes may affect the phenotypes of lipid metabolism.展开更多
