People who have PKD were born with it. PKD is almost always inherited from a parent or from both parents. People of all genders, ages, races, ethnicities and nationalities can have PKD. Men and women get PKD equally as often. If you have a blood relative with PKD, you are more likely to have PKD or carry the gene that causes it. If you carry the gene that causes PKD but you do not have the disease, you are called a carrier. This is possible with autosomal recessive PKD.
