Brief summary: Steroid analysis using LC-MS/MS in association with clinical parameters may be used to develop a diagnostic score that could successfully differentiate premature pubarche (PP) from non-classic congenital adrenal hyperplasia (NCCAH), thereby obviating the need for ACTH stimulation testing.Late onset, non-classic congenital adrenal hyperplasia (NCCAH) due to 21-hydroxylase deficiency (21-OHD) should be ruled out in children with premature pu...

Brief summary: Over the recent years several publications reported on next generation sequencing (NGS) in cohorts of patients with congenital hypothyroidism (1). Based on these data, diagnostic yield was higher in patients with gland-in-situ, than with thyroid dysgenesis. Further studies performed NGS only in cohorts of patients with gland-in-situ, excluding thyroid dysgenesis forms such as athyreosis, ectopy, or hypoplasia (2). The publication of Levaillant ...
