Final answer:
Polycystic kidney disease (PKD) is a genetic disorder in which multiple abnormal cysts develop and grow in the kidneys. It can be inherited from parents and is not associated with a streptococcal infection or supernumerary kidney. While PKD can lead to kidney failure, it is not always rapidly fatal.
