Integrating genetic counseling in endocrine practice: Prevention, reproductive care, and prenatal diagnosis.

Genetic counseling has become a cornerstone of care in inherited endocrine and metabolic disorders, complementing clinical evaluation with molecular diagnosis and personalized risk assessment. In endocrinology, although many conditions are initially suspected based on clinical and biochemical findings, genetic testing refines diagnosis, clarifies prognosis, and guides long-term management including genetic counselling. Identification of pathogenic variants in genes such as MEN1, NR5A1, GNAS, PHEX, or CYP21A2 enables tailored surveillance, early detection of complications, and cascade screening of at-risk relatives. Beyond individual patient care, genetic counseling plays a pivotal role in reproductive medicine. By explaining inheritance patterns, including autosomal dominant, autosomal recessive, X-linked transmission, and imprinting mechanisms, it allows accurate estimation of recurrence risks and informed reproductive decision-making. Carrier detection, partner screening, prenatal diagnosis, and preimplantation genetic testing are integral components of this approach, particularly in disorders with significant morbidity or variable expressivity. Genetic consultation is also essential in the management of fetal anomalies detected on ultrasound. It supports diagnostic clarification, proposes appropriate molecular investigations, refines prognostic assessment, and addresses recurrence risk in future pregnancies. Importantly, counseling provides psychosocial support, helping families navigate uncertainty and complex medical decisions. Overall, integrating genetic counseling into endocrine practice promotes prevention, optimizes follow-up, enhances reproductive care, and fosters a proactive, family-centered model of management in hereditary endocrine diseases.
