title: Association of apolipoprotein E polymorphism with lipoprotein glomerulopathy. Report of 2 cases with a new genotype and comparison of the relative frequencies of apolipoprotein E isoforms in lipoprotein glomerulopathy and in the general population.
abstract: Two cases of lipoprotein glomerulopathy with a new apolipoprotein E (Apo E) genotype, epsilon3/epsilon4, were diagnosed recently. These 2 cases, together with other cases documented in English literature made a total of 6 common isoforms of Apo E encountered in lipoprotein glomerulopathy. Although the calculated allele frequency of epsilon2 is relatively high in cases with lipoprotein glomerulopathy as compared with that in the general population (39.3 vs. 6.4-11.4%), the gradual emergence of Apo E isoforms other than E2/E3 in lipoprotein glomerulopathy implicates that the genetic susceptibility of certain Apo E isoforms may not be a crucial factor. An alteration in the local environment of glomerular capillaries may be more important in the pathogenesis of lipoprotein glomerulopathy.
