+ Polycystic Kidney Disease Anne Campbell

+ Polycystic Kidney Disease Genetic Disease Normal kidney tissue is replaced with fluid filled cysts 600K People suffer from PKD

+ Characteristics of PKD Enlargement of the Kidneys Formation of fluid filled cysts Pain

+ Characteristics of PKD Renal Failure Complications with other organs 2 types of PKD

+ Recessive vs. Dominant Rare Infantile Must inherit 2 copies to express symptoms 25% chance Common type of PKD Adult PKD Can inherit from a single parent 50% chance Autosomal Recessive PKDAutosomal Dominant PKD

+ 10% of cases arise spontaneously Symptoms appear around years of age lb kidneys No cure, treat symptoms (high blood pressure, pain)

+ Autosomal Recessive PKD Signs can begin before birth Enlarged, abnormal kidneys Developmental issues Kidney failure early on Liver scarring- worsens with age No cure, treat symptoms Worse cases- live only hours or days

+ Genetics of PKD Autosomal Dominant: PKD1 and PKD2 (chr.16 and chr.4) Polycystin-1 and polycystin-2 Autosomal Recessive: PKDH1 (chr.6)
