What is the Origin of CAG Repeats?

The term originates from the molecular genetics domain, specifically relating to the study of trinucleotide repeat polymorphisms, which are common sources of genetic variability. This particular CAG sequence is highly conserved but varies in copy number across the human population, typically ranging from about 10 to 36 repeats. Pathological expansion beyond the normal range is known to cause severe neurodegenerative disorders, such as Spinal and Bulbar Muscular Atrophy.

What is the Mechanism of CAG Repeats?

The mechanism is one of inverse correlation: a shorter CAG repeat length generally translates to a more transcriptionally active androgen receptor, leading to a stronger cellular response to circulating testosterone. Conversely, longer repeats result in diminished receptor function, which can manifest as symptoms of androgen deficiency despite normal serum testosterone concentrations. This genetic modulation influences diverse androgen-dependent processes, including spermatogenesis, muscle protein synthesis, bone density maintenance, and potentially the risk profile for prostate cancer. Clinical interpretation of serum testosterone levels must therefore consider this intrinsic genetic variability in receptor function.

CAG Repeats

Meaning

CAG Repeats refer to a variable length sequence of cytosine-adenine-guanine trinucleotides located within the exon 1 region of the Androgen Receptor (AR) gene. This polymorphic sequence encodes a polyglutamine tract in the receptor protein that directly modulates its functional transcriptional activity. The length of this repeat segment is a critical genetic factor influencing an individual’s physiological sensitivity to androgens like testosterone and dihydrotestosterone. Variations in this sequence can lead to significant differences in hormonal response, even among individuals with identical circulating hormone levels.
