What is Hydrolethalus Syndrome?
A rare lethal autosomal recessive malformation syndrome caused by mutations in the HYLS1 gene (a ciliary protein), characterized by severe hydrocephaly, a keyhole-shaped defect in the occipital bone (absent midline posterior fossa structures), polydactyly, and multiple organ defects. It is one of the most severe of the ciliopathy group and is uniformly lethal.
Questions About Hydrolethalus Syndrome
How do you pronounce 'hydrolethalus syndrome'?

Say it like this: hy-droh-LEE-thal-us SIN-drohm. The stress falls on the second syllable of the first word (LEE), so you emphasize that part when speaking. The second word, syndrome, is pronounced with stress on the first syllable (SIN).

Break it into five parts: hy-dro-le-thal-us. When you say it out loud, remember to punch the LEE sound—that's where the stress lands.
What's a common mispronunciation of this word?

Many people stress the wrong syllable and say hy-DROH-lethal-us, but that's incorrect. The correct way puts the stress on LEE: hy-droh-LEE-thal-us. This is an easy mistake because the 'dro' part sounds strong, but it's not the stressed syllable.

'Hydro' comes from Greek and means water—it refers to excess fluid in this condition. 'Lethal' comes from Latin and means deadly or fatal. 'Syndrome' means a group of signs or features that occur together. So the name describes a serious condition involving fluid buildup.
Are there any related words that share the 'hydro' root?

Yes! Words like hydrocephalus (fluid in the brain), hydration (adding water to the body), and hydrotherapy (treatment using water) all start with 'hydro.' They all connect to the idea of water or fluid in some way.
What's the simplest way to explain what 'hydrolethalus syndrome' means?
+
The name combines three ideas: water (hydro), deadly (lethal), and a group of related features (syndrome). It's a medical term for a very serious rare condition, but the word itself just describes that it involves fluid and is severe.
How would you use this term in a sentence?
+
You might hear it in a medical classroom or textbook like this: 'The doctor explained that hydrolethalus syndrome is an example of a ciliopathy, which is a disorder affecting cell structures.' The term is mainly used by medical professionals and in medical education.
Is there a short abbreviation for hydrolethalus syndrome?
+
Sometimes it is abbreviated as HLS, though this abbreviation is not as commonly used as abbreviations for other medical conditions. When you see HLS in a medical text, the full term 'hydrolethalus syndrome' is what it stands for.
