Pronunciation: [pˌɒlɪɡlˈuːtɐmˌiːn tɹˈakt] (IPA) 
Polyglutamine tract is a term used to describe a repetitive stretch of amino acids consisting of glutamine residues in a protein chain. This sequence is commonly associated with neurodegenerative diseases such as Huntington's disease. Although "polyglutamine tract" is the most commonly used term, other synonyms include "polyQ tract", "polyQ expansion", "CAG repeat expansion", "long CAG repeat", "CAG trinucleotide repeat", and "polyglutamine expansion". These terms are used interchangeably to refer to the number of repeats of the CAG trinucleotide in the DNA coding the protein, which directly influences the length of the polyglutamine tract in the protein sequence.
