What is the Meaning of CAG Repeat?

The CAG Repeat denotes a specific sequence of three nucleotides, Cytosine-Adenine-Guanine, that is tandemly repeated within a gene's structure. In clinical genetics, the length of this trinucleotide repeat is directly correlated with the risk and severity of certain inherited disorders. For instance, in the context of hormonal health, its length within the Androgen Receptor gene is clinically significant. An abnormal expansion of these repeats dictates the phenotypic expression.

What is the Origin of CAG Repeat?

This term arises from molecular biology and genetics, where 'CAG' represents the specific codon sequence transcribed from DNA. 'Repeat' refers to the physical repetition of this sequence along the chromosome strand. Its relevance in endocrinology is tied to genes encoding steroid hormone receptors.

What is the Mechanism of CAG Repeat?

The mechanism of action relates to the encoded protein structure; specifically, the polyglutamine tract formed by the repeated CAG codons in the receptor protein. Excessive repeats often lead to protein misfolding or instability, compromising ligand binding or transcriptional activity. In the case of the Androgen Receptor, expanded CAG repeats cause a loss of function, clinically presenting as aspects of hypogonadism or androgen insensitivity.
