Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...
