What is 21-Hydroxylase Deficiency?
The most common form of congenital adrenal hyperplasia (accounting for 90-95% of cases), caused by deficiency of 21-hydroxylase enzyme, resulting in impaired cortisol and aldosterone synthesis with compensatory androgen overproduction. The classic form presents with either salt-wasting crisis in newborns or virilization of female genitalia at birth.
Questions About 21-Hydroxylase Deficiency
How do you pronounce '21-Hydroxylase Deficiency'?
+
Say it like this: TWEN-tee-wun hy-DROK-sih-lays deh-FISH-en-see. The stress falls on TWEN (the first syllable of "twenty-one") and on DROK (the second syllable of "hydroxylase"). The last part, "deficiency," is pronounced deh-FISH-en-see with stress on the FISH syllable.
What's the most common mistake people make when saying this term?
+
Many people stress the wrong syllable in "hydroxylase" — they say hy-DROK-sih-lase when they should say hy-DROK-sih-lays (rhyming with "laze," not "lace"). Also, some people rush through "21" instead of clearly saying "twenty-one."
Can you break this term into syllables for me?
+
Here's how it breaks down: twen-tee-wun / hy-DROK-sih-lays / deh-FISH-en-see. Notice the number "21" becomes three syllables (twen-tee-wun), the enzyme name has four syllables, and "deficiency" has four syllables.
What does 'hydroxylase' mean?
+
"Hydroxylase" comes from Greek and Latin roots: "hydroxy" refers to a chemical group containing hydrogen and oxygen, and "-lase" is a suffix meaning "enzyme." So a hydroxylase is an enzyme that adds or moves a hydroxy group in chemical reactions inside the body.
Is there a shorter way to write or say this condition?
+
Yes! It's often abbreviated as 21-OH deficiency or CAH (congenital adrenal hyperplasia). When doctors abbreviate it to "21-OH," they just say "twenty-one oh" or "21 hydroxylase deficiency" for short in conversation.
What other medical words share the 'hydroxylase' root?
+
You'll see "hydroxylase" in other enzyme names like 11-beta-hydroxylase and 17-hydroxylase — they're all enzymes with different jobs in the body. Once you know what hydroxylase means, these related terms become easier to understand.
What does this term mean in plain English?
+
In simple terms, it means the body is missing or has very low levels of a specific enzyme (21-hydroxylase) that normally helps make certain important chemicals. When this enzyme doesn't work properly, those chemicals don't get made the way they should.
How would you use this word in a sentence?
+
Here's an example: "The lab results showed that the patient has 21-hydroxylase deficiency." Or: "21-hydroxylase deficiency is the most common type of congenital adrenal hyperplasia."
