What is MHC Class II Deficiency?
A rare form of combined immunodeficiency in which the major histocompatibility complex class II molecules — essential for presentation of antigens to CD4+ T helper cells — are absent or severely reduced due to mutations in transcription factors (CIITA, RFX5, RFXANK, or RFXAP). It causes severe susceptibility to viral, fungal, and bacterial infections and presents similarly to SCID, requiring bone marrow transplantation.
Questions About MHC Class II Deficiency
How do you say MHC Class II Deficiency?
+
Say it as EM-AYCH-SEE KLAS TOO deh-FISH-en-see. The stress falls on the first part (EM), and then you say the letters M, H, C separately. The word "deficiency" at the end rhymes with "fish" at the start.
What does MHC stand for?
+
MHC is short for "Major Histocompatibility Complex." You pronounce each letter separately: EM-AYCH-SEE. It's a medical abbreviation, so doctors and scientists often just say the letters instead of the full name.
Why is the stress on the first syllable of 'deficiency'?
+
In medical English, "deficiency" is stressed on the second syllable: deh-FISH-en-see. A common mistake is stressing the first syllable (DEF-ish-en-see), but that's not correct. Remember: deh-FISH is the stressed part.
What does 'Class II' mean in this term?
+
"Class II" refers to one type of molecule in the immune system, and you say it as "Class Two." It's called "Class II" to distinguish it from "Class I"—there are different types of these immune molecules, labeled with Roman numerals.
What does 'deficiency' mean in plain English?
+
Deficiency means a lack or shortage of something. So "MHC Class II Deficiency" means there is a shortage or absence of these particular immune molecules. It's the opposite of having plenty of something.
How do you break MHC Class II Deficiency into syllables?
+
Break it like this: EM / AYCH / SEE / KLAS / TOO / deh / FISH / en / see. That's nine syllables total. The biggest stress is on the first syllable (EM), and the second biggest stress is on FISH in the word deficiency.
What is a common mispronunciation of this term?
+
A common mistake is saying "em-aych-see CLASS-two" with stress on "class" instead of on "em." Another mistake is saying "deFISHency" instead of "deh-FISH-en-see." Keep the stress on the beginning and middle parts of the word, not at the end.
