In conclusion, the expression of Exo-1 in cyst-lining epithelial cells of autosomal dominant polycystic kidney disease (ADPKD) and the altered regulation of TGF-alpha and EGF receptor in these cells contribute to the hypothesis that hyperproliferation is an underlying pathogenic mechanism of ADPKD.

Although most mutations causing ADPKD in European populations have been mapped to the PKD1 locus on chromosome 16, some of them appear to be unlinked to this locus.
We have mainly used 3 highly polymorphic DNA markers, 3'HVR (D16S85), 16AC2.5 (D16S291) and SM7 (D16S283), flanking the PKD1 region on chromosome 16p13.3 to establish linkage status in seven Icelandic families with autosomal dominant polycystic kidney disease (ADPKD).
Assuming that a clinic population represents the most severe forms of a disease and non PKD-1 is a less aggressive phenotype, the degree of genetic heterogeneity for APKD in the population may well be much greater than at present suggested.
Genetic linkage studies were carried out in 11 relatives (4 with ADPKD), and on fetal DNA obtained from cultured amniocytes, using 8 flanking DNA markers tightly linked to the PKD1 locus on chromosome 16p, and a DNA marker linked to another putative ADPKD locus on chromosome 2p.
Furthermore, when flanking markers for the second ADPKD gene are used in conjunction with flanking markers for PKD1, the accuracy of the diagnosis of the subtype of ADPKD present in any particular family will be enhanced.
In autosomal dominant polycystic kidney disease 1) the genetic localization of the defective gene that causes type 1 disease has been narrowed to 500 to 750 kb on chromosome 16; 2) cystogenesis has been associated with increased cell proliferation, continuing cyst secretion, and a defect in cell polarity; however, the mechanisms by which the genetic defects in autosomal dominant polycystic kidney disease translate into cyst formation are unknown; 3) activation of the renin system has been reported as an important potential cause of hypertension; and 4) factors that influence the progression to renal failure have been identified.

Other genes mapped to this area (16p13.3) include phosphodiesterase IB (PDE1B), hydroxyacyl-glutathione hydrolase (HAGH), phosphoglycolate phosphatase (PGP), and the gene that causes adult polycystic kidney disease (PKD1).

Immunohistochemically subepithelial fibrous tissue of cyst walls in ADPKD kidneys showed strong coexpression of both undulin and tenascin with marked intensity adjacent to cyst-lining epithelium.

Linkage analysis in 19 families with autosomal recessive polycystic kidney disease (ARPKD) has shown that ARPKD is not linked to the recently assigned second gene locus for autosomal dominant polycystic kidney disease (ADPKD) on chromosome 4q (PKD2).
