Can Chronic Kidney Disease Be Inherited

 Chronic kidney disease (CKD) can have genetic and non-genetic causes. Some types of CKD can be inherited, while others are acquired through lifestyle or environmental factors.


Inherited forms of CKD include:


Autosomal dominant polycystic kidney disease (ADPKD): This is the most common inherited form of kidney disease, accounting for 5-10% of all cases of CKD. ADPKD is caused by mutations in the PKD1 or PKD2 genes, which produce proteins involved in the formation of kidney cells. In ADPKD, cysts (fluid-filled sacs) develop in the kidneys and can grow over time, eventually leading to kidney failure.


Alport syndrome: This is a rare genetic condition caused by mutations in the COL4A3, COL4A4, or COL4A5 genes, which produce proteins that help form the glomeruli (the filtering units of the kidney). Alport syndrome can cause kidney damage and hearing loss, and can lead to kidney failure in some cases.

If you have any medical problem, consult a good doctor. 

If you follow these medical advices, do so at your own risk.


Fabry disease: This is an inherited metabolic disorder caused by mutations in the GLA gene, which produces an enzyme called alpha-galactosidase A. Without this enzyme, a fatty substance called globotriaosylceramide (Gb3) builds up in the kidneys and other organs, causing damage over time.


Other forms of CKD may have a genetic component, but are not directly inherited in a simple pattern. For example, certain genetic variations may increase the risk of developing CKD in response to other factors, such as high blood pressure or diabetes.


It is important to note that not all cases of CKD have a genetic cause, and lifestyle factors such as diet, exercise, and tobacco use can also play a significant role in the development and progression of CKD.
