What is the Meaning of CAG Repeat?

A CAG repeat is a specific trinucleotide DNA sequence (cytosine, adenine, guanine) repeated consecutively within certain genes. This sequence codes for the amino acid glutamine. Expansion of these repeats beyond a normal threshold indicates genetic instability, associated with inherited neurodegenerative disorders.

What is the Context of CAG Repeat?

These repeats reside within coding regions of specific genes throughout the human genome. The precise length of the CAG repeat tract is crucial for proper protein function. While a normal range is necessary, abnormal expansion alters the protein's structure and behavior, compromising cellular health.

What is the Significance of CAG Repeat?

The length of a CAG repeat tract holds considerable clinical importance as a diagnostic marker for inherited neurological conditions, including Huntington's disease and various spinocerebellar ataxias. Identifying an abnormal expansion provides definitive diagnosis, aids in predicting disease onset, and correlates with symptom severity. This genetic insight is fundamental for patient management.

What is the Mechanism of CAG Repeat?

Pathological effects occur when the CAG repeat sequence expands beyond a critical threshold, leading to an elongated protein with an abnormally long polyglutamine tract. This extended protein often misfolds and aggregates within cells, particularly neurons, forming insoluble clumps. These aggregates disrupt normal cellular functions, inducing cellular toxicity and clinical manifestations.

What is the Application of CAG Repeat?

Genetic testing for CAG repeat expansion is a standard clinical procedure. It confirms diagnoses in symptomatic individuals or provides predictive testing for at-risk family members. This offers vital information for genetic counseling, enabling understanding of genetic status, prognosis, and reproductive options. Such knowledge supports informed health planning.

What is the Metric of CAG Repeat?

The number of CAG repeats is precisely quantified using molecular genetic techniques. Typically, polymerase chain reaction (PCR) amplification of the relevant gene region, followed by fragment analysis or direct DNA sequencing, is employed. The data yields an exact count, compared against established normal and pathological ranges to determine genetic status.

What is the Risk of CAG Repeat?

Genetic testing for CAG repeat expansion presents psychosocial risks, especially for pre-symptomatic individuals. A positive result can lead to significant distress, as effective treatments are often unavailable. Ethical considerations regarding privacy, genetic discrimination, and family implications necessitate comprehensive genetic counseling to support individuals through this process.
