Preeclampsia/eclampsia 2
For a general phenotypic description and a discussion of genetic heterogeneity of preeclampsia, see PEE1 (189800).
MappingHypothesizing that the genetic background of preeclampsia might show reduced heterogeneity in a founder population such as that of the Kainuu province in central eastern Finland, Laivuori et al. (2003) performed a genomewide scan in 15 multiplex families in that area. They found 2 loci that exceeded the threshold for significant linkage: 2p25 (PEE2), at 21.70 cM, and 9p13 (PEE3; 609403), at 38.90 cM. They concluded that the susceptibility locus on 2p25 was clearly different from the locus (PEE1) at 2p13 found in the Icelandic study of Arngrimsson et al. (1999).
