Exon 1 of AR gene contains a variable number of CAG triplets, which encode a polyglutamine stretch of variable length in the N-terminal domain of the receptor. Experimental evidence has accumulated in demonstrating that the length of this stretch influences AR transcriptional activity and therefore modulates target organs responsiveness to androgens. Aim of our study was to evaluate CAG repeats length [(CAGr)n] in various conditions hypothetically influenced by AR function. 35...

Thyroid hormone resistance (THR) and pituitary TSH-secreting adenomas (TSHoma) are both characterised by increased serum free thyroid hormone levels and normal TSH concentrations. Differentiation of the two syndromes is a clinical challenge, and relies on the suppression (TRH) or lack of suppression (TSHoma) of TSH-dependent parameters and on the presence of germinal mutations in the thyroid hormone receptor beta 1 gene in patients with THR. Thyroid blood flow, evaluated using...
