Autosomal Dominant Tubulointerstitial Kidney Disease (ADTKD)

Pathophysiology

Structure

• Kidneys: The kidneys are bean-shaped organs responsible for filtering blood, producing urine, and maintaining fluid and electrolyte balance.
• Nephrons?: Each kidney contains about a million nephrons, which are the functional units made up of tubules and glomeruli?.
• Tubules: These are small tubes that reabsorb essential substances from urine and secrete waste.

Blood Supply

• The kidneys receive blood through the renal? arteries?. They filter blood, removing waste and excess substances while retaining necessary components.

Nerve Supply

• The kidneys are innervated by the autonomic nervous system, which regulates blood flow and other functions.

Types of ADTKD

1. ADTKD-UMOD: Caused by mutations in the UMOD gene.
2. ADTKD-MUC1: Linked to MUC1 gene mutations.
3. ADTKD-TGFβ1: Involves mutations in the TGFβ1 gene.
4. ADTKD-FLCN: Related to mutations in the FLCN gene.

Causes of ADTKD

ADTKD is caused by inherited? genetic mutations. Here are 20 potential causes:

1. UMOD gene mutation: Involves abnormal uromodulin production.
2. MUC1 gene mutation: Affects mucin protein production.
