Background: Congenital hypothyroidism (CH) is a heterogeneous disorder. While the great majority of cases are considered sporadic, the use of next generation sequencing (NGS) may bring significant advances in elucidating the underlying molecular mechanisms.Case presentation: We selected a family with three children affected by CH with gland in situ and diagnosed at neonatal screening: the index patient, his sister and his brother. Data at diagno...

Introduction: The underlying genetic causes of congenital hypothyroidism with gland in-situ (CH GIS) and hyperthyrotropinemia (HT) remain largely a mystery. Thanks to NGS, genetic screening is now finding many novel variants. The challenge is to correctly identify which genes and which variants lead to CH and which cause only a transient HT.Objectives: Our objectives were to evaluate the presence of variants in 14 candid...

Background: Over the years special screening procedures for preterm and twin babies (re-screening at 2–4 weeks of life) have been adopted by many screening laboratories worldwide. However, no extensive studies have been performed to verify how many co-twins with negative test at first screening (3–5 days) become positive at re-screening, and the utility of a long-term follow-up also in co-twin with negative test at screening and re-screening.Ob...
