Adult polycystic kidney disease (APKD) is a common genetic disease and one of the important reasons of end stage renal failure. Although renal multiple cysts are clearly an important manifestation of APKD; other systemic manifestations are both common and clinically important. The authors reviewed 205 cases from 180 APKD families (107 male 98 female). Their age ranged from 10 to 71 years. Renal cyst is one of the many renal manifestations. Hypertension, hematuria and flank pain are its major complications. Hepatic cysts, pancreatic cysts, cardiac valvular lesions, intracranial aneurysms and splenic cysts are included in the array of systemic manifestations.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease, but poorly studied in Africa. Its frequency in the University Clinic of Nephrology and Hemodialysis of Cotonou during the ten last years was 7 cases per year with a hospital prevalence estimated at 18 per 1000. The mean age of patients was 47.2 years extending from 29 to 70 years. Males were predominant with a sex ratio of 1.13. Family history was found in 47% of patients. The most common manifestations were lumbar pain (62%), high blood pressure (59%) urinary tract infections (53%), hematuria (46%), and abdominal masses (43%). Hepatic cysts were the most extra renal manifestations, found in 34% of cases. Renal failure was observed in 72% of patients of our series, six of them were under dialysis. Direct sequencing of polycystin 1 gene enabled us to identify some new mutations: 4 nonsense mutations (p.Q2824X exon 23, p.Q1651X exon 15, p.W1666X exon 15, p.R966W exon 12), a duplication (c_1761.1745 dup exon 9), a deletion (c.9397 + 1_9397 + 8del intron 26) and a deletion-insertion (c.7290_7291delins CTGCA exon 18).

Polycystic kidney disease (PKD) is a systemic disorder which adds majority of renal patients to end stage renal disease. Autosomal dominant polycystic kidney disease (ADPKD) is more prevalent and leading cause of dialysis and kidney transplant. Linkage analysis revealed some closely linked loci, two of which are identified as PKD1, PKD2 and an unidentified locus to ADPKD. This study was performed using PCR and automated DNA sequencing in 84 cases and 80 controls to test potential candidature of PKD2 as underlying cause of PKD by in silico and statistical analyses. Two associated symptoms, hypertension (19%) and liver cyst (31%) havemajor contribution to PKD. Gender-based analysis revealed that familial female patients (27%) and familialmale patients (33%) are more hypertensive. Liver cyst, the second major contributing symptom presented by large percentage of sporadic males (46%). Genetic screening of all 15 exons of PKD2 revealed eight pathogenic (c.854_854delG, c.915C>A, c.973C>T, c.1050_1050delC, c.1604_1604delT, c.1790T>C, c.2182_2183delAG, c.2224C>T) and eight likely pathogenic (g.11732A>G, c.646T>C, c.1354A>G, g.39212G>C, c.1789C>A, c.1849C>A, c.2164G>T, c.2494A>G)DNA sequence variants. In our study, 27.38% (23/84) cases shown pathogenic / likely pathogenic variants in PKD2 gene. Some regions of PKD2 prone for genetic variation suggested to be linked with disease pathogenesis. This noticeable hot spot regions hold higher frequency (50%) of pathogenic / likely pathogenic genetic variants constituting single nucleotide variants than large deletion and insertion that actually represents only 41.08% of coding sequence of PKD2. Statistically significant association for IVS3-22AA genotype was observed with PKD, while association of IVS4+62C>T was found insignificant.
