Definition

1. Noun:
   • A genetic disorder affecting the kidneys: PKD is an abbreviation for Polycystic Kidney Disease. It is a condition where numerous fluid-filled cysts develop in the kidneys, causing them to become enlarged. This can lead to a decline in kidney function over time, potentially resulting in kidney failure.

Usage Examples

• Noun:
  • The patient was diagnosed with PKD after a family history review and imaging tests.
  • Managing high blood pressure is crucial for slowing the progression of PKD.
  • Research into new treatments for PKD is ongoing.

Advanced Usage

• "Autosomal Dominant PKD (ADPKD)": The most common inherited form of the disease, where only one copy of the abnormal gene is needed to cause the disorder.
  • Autosomal Dominant PKD typically presents symptoms in adulthood.
• "Autosomal Recessive PKD (ARPKD)": A rarer form that is often diagnosed in infancy or childhood and requires two copies of the abnormal gene.
  • Autosomal Recessive PKD is a severe form that can affect the liver as well as the kidneys.

Variants and Related Words

• Polycystic Kidney Disease (n): The full name for PKD.
  • Polycystic Kidney Disease is one of the most common life-threatening genetic diseases.
• Cyst (n): A closed sac-like structure, which is the primary abnormality in PKD.

Synonyms

• Polycystic Kidney Disease: The full, non-abbreviated term.

Notes on Usage

• PKD is primarily used as a medical acronym. In formal writing, it is often introduced by its full term, "Polycystic Kidney Disease (PKD)," after which the abbreviation can be used alone.
• It functions as a singular noun (e.g., PKD a genetic disorder).
• This term does not have associated phrasal verbs or idioms in common English usage, as it is a specific medical condition.
