Congenital Adrenal Hyperplasia Clinical Insights
Summary
Congenital adrenal hyperplasia (CAH) encompasses a group of inherited disorders of steroidogenesis, most commonly due to 21-hydroxylase deficiency, that lead to impaired cortisol synthesis, compensatory adrenocorticotrophic hormone elevation and androgen excess. Clinical manifestations range from life-threatening salt-wasting crises in the neonatal period to nonclassic forms presenting with mild virilisation or menstrual irregularities in adolescence and adulthood. Timely diagnosis, often through newborn screening or biochemical profiling, enables early institution of glucocorticoid and mineralocorticoid replacement to prevent adrenal crisis, manage androgen excess and support normal growth and development. Despite advances in hormone assays, genetic testing and therapeutic formulations, long-term complications include cardiometabolic risk, impaired bone health, fertility challenges and quality-of-life concerns. Recent translational efforts have focused on optimising hormone delivery, improving genetic diagnosis through high-resolution techniques and elucidating the molecular basis of alternative androgen pathways. Integrating endocrinological, genetic and psychosocial perspectives is essential to advance personalised care and mitigate lifelong morbidity.

Congenital Adrenal Hyperplasia Clinical Insights publication trend
The graph below shows the total number of articles in congenital adrenal hyperplasia clinical insights across all publications each year (not limited to Nature Index journals).
Technical terms
21-Hydroxylase deficiency: A genetic defect in the CYP21A2 enzyme leading to impaired cortisol and aldosterone synthesis.
Glucocorticoid replacement: Administration of cortisol analogues to suppress excess adrenocorticotrophic hormone and restore homeostasis.
Mineralocorticoid replacement: Use of aldosterone analogues to maintain sodium balance and prevent salt wasting.
Androgen excess: Elevated levels of male sex steroids resulting in virilisation and metabolic effects.
Long-read sequencing: A genomic technique that generates extended DNA reads, permitting resolution of complex gene regions and structural variants.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
