What is the Meaning of CAG Repeats?

CAG Repeats are specific DNA sequences, Cytosine-Adenine-Guanine, found repeatedly within certain genes. Pathological expansion of these trinucleotide units beyond a normal range leads to proteins with abnormally long polyglutamine tracts. These expanded tracts disrupt cellular function, marking inherited neurodegenerative disorders.

What is the Context of CAG Repeats?

These genetic expansions occur within coding regions of genes, translating into altered proteins. They associate primarily with inherited neurodegenerative polyglutamine diseases, including Huntington's disease and various spinocerebellar ataxias. The length of these repeats directly influences disease onset and severity, predominantly affecting the central nervous system.

What is the Significance of CAG Repeats?

Clinically, CAG repeat expansions are critical diagnostic markers for progressive neurological disorders. Their identification provides a definitive diagnosis, enabling precise genetic counseling and allowing clinicians to anticipate symptom trajectories. Understanding repeat length aids prognostic assessment and informs family planning for affected individuals.

What is the Mechanism of CAG Repeats?

The pathogenic effect of expanded CAG repeats stems from their transcription and translation into proteins with abnormally long glutamine segments. These elongated polyglutamine tracts cause proteins to misfold, aggregate, and accumulate within specific neuronal populations. This leads to cellular toxicity, progressive neuronal dysfunction, and eventual cell death, resulting in neurological symptoms.

What is the Application of CAG Repeats?

Clinical application of CAG repeat analysis involves genetic testing for individuals presenting with symptoms or those at genetic risk. This diagnostic process employs molecular techniques to precisely quantify the number of CAG repeats within the relevant gene. Results inform patient management, guide early intervention, and are fundamental for clinical trial participation.

What is the Metric of CAG Repeats?

Measurement of CAG repeats is performed through molecular genetic assays, usually on DNA extracted from a blood sample. Techniques like polymerase chain reaction or fragment analysis accurately quantify the number of trinucleotide repeats. A specific threshold for pathogenicity exists; more repeats often correlate with earlier onset and increased disease severity.

What is the Risk of CAG Repeats?

Genetic testing for CAG repeat expansions carries significant implications, particularly without comprehensive genetic counseling. Misinterpretation, psychological distress, and absence of disease-modifying treatments present challenges. Potential for discrimination and family impact must be carefully considered within a supportive clinical framework.
