Huntington's disease (HD) is an autosomal dominant neurodegenerative condition associated with abnormal movements, cognitive deterioration, and psychiatric symptoms. (bmj.com)

At the molecular level, HD occurs due to an increase in the number of CAG repeats in the first exon of the gene encoding the huntingtin protein. (frontiersin.org)
It is caused by the expansion of cytosine-adenine-guanine (CAG) trinucleotide repeats in the huntingtin ( HTT ) gene on chromosome 4, which is responsible for the expression of the protein huntingtin ( Nance, 2017 ). (frontiersin.org)
The age of onset of the disease varies inversely with the number of CAG repeats. (jci.org)
Individuals with juvenile onset usually have over 55 repeats, and they usually inherit the gene from their father. (jci.org)
The higher the number of CAG repeats, the earlier the age of onset and the greater the severity of the disease. (medicalnewstoday.com)
An expansion of 36 or more CAGs can lead to the disease, with earlier onsets associated with longer CAG repeats. (biomedcentral.com)
Huntington Disease (HD) is a hereditary neurological disorder that shows a gene expansion associated with trinucleotide repeats. (medicalalgorithms.com)
The HTT mutation that causes Huntington disease is because of a DNA section known as CAG trinucleotide (made of the three bases cytosine, adenine and guanine) which repeats. (nmmra.org)
In a normal gene, the CAG segment repeats 10 to 35 times, however in a person with HD, the segment is repeated 36 to 120 times. (nmmra.org)
Because this person has more than the needed amount of CAG repeats, it leads to an irregular size of the huntingtin protein. (nmmra.org)
As the gene is inherited from one generation to another, the number of CAG repeats increases in size. (nmmra.org)
A larger number of repeats of the CAG segment results in developing the disease earlier in life. (nmmra.org)
HTT gene usually see signs of the disease later on in life, while people with more than 50 repeats tend to see it earlier. (nmmra.org)
The normal number of CAG repeats is 10-35 times, however, in HD this repeat will occur 36 times or more and as CAG codes for glutamine, HD is classified as a polyglutamine disease. (edubirdie.com)

OBJECTIVES Recent data suggest that wild type huntingtin can protect against apoptosis in the testis of mice expressing full length huntingtin transgenes with expanded CAG repeats. (bmj.com)
METHODS We cotransfected neuronal (SK-N-SH, human neuroblastoma) and non-neuronal (COS-7, monkey kidney) cell lines with HD exon 1 (containing either 21 or 72 CAG repeats) construct DNA and either full length wild type huntingtin or pFLAG (control vector). (bmj.com)
RESULTS Full length wild type huntingtin significantly reduced cell death resulting from the mutant HD exon 1 fragments containing 72 CAG repeats in both cell lines. (bmj.com)
Wild type huntingtin did not significantly modulate cell death caused by transfection of HD exon 1 fragments containing 21 CAG repeats in either cell line. (bmj.com)
The causative mutation is a (CAG) n trinucleotide repeat expansion of more than 35 repeats, which is translated into an abnormally long polyglutamine tract in the huntingtin protein. (bmj.com)
The more CAG repeats, the earlier the onset of disease and the more severe its expression (phenotype). (msdmanuals.com)
Specifically, it occurs in the CAG repeats of the gene, which consists of a cytosine-adenine-guanine repetitive DNA sequence that codes for a polyglutamine amino acid sequence, with glutamine being the corresponding amino acid for these triplet bases. (essex.ac.uk)
This mutation causes an expansion of these repeats, leading to the production of abnormal, misfolded huntingtin protein (Nopoulos, 2016) (Figure 2). (essex.ac.uk)

The mutation is in the HTT gene that codes for the protein huntingtin (Figure 1). (essex.ac.uk)
