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...

Introduction: Although there are several studies on the incidence of congenital hypothyroidism (CH), there are few data showing incidence and evolution of CH detected by the second newborn screening (NBS).Objectives: To assess the incidence of CH in Lombardia region and the percentage of patients identified by the 2ndNBS. To describe the clinical features and evolution of CH patients detected by the 2nd</...

Introduction: Hyperinsulinaemic Hypoglycaemia (HH) is one of the commonest causes of hypoglycaemia in infancy. It is characterised by hypoketotic, hypofattyacidaemic and hyperinsulinaemic hypoglycaemia. The molecular basis of HH includes defects in pathways that regulate insulin release; to date, 12 genes have been associated with monogenic forms of HH (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1, PMM2). However, no genetic aetiology has been...

Background: National and international guidelines recommend thyrotropin (TSH) determination as the most sensitive test for detecting primary congenital hypothyroidism (CH) in newborn screening programs. A strategy of a second screening at 2 weeks of age, or 2 weeks after the first screening was carried out, is also recommended in preterm, LBW and VLBW neonates, twins, neonates admitted in NICU, and babies with specimen collection within the first 24 hours of life [1–3]. H...

Background: In a recent report we have identified multinodular goiter (MNG) as a condition with an increased risk for thyroid malignancy in children and adolescents.Objective and hypotheses: To report the prevalence and characterization of a prospectively and uniformly followed cohort of pediatric patients with MNG and to retrospectively analyze differences between benign and malignant MNG before surgery in order to identify malignancy predictors.<p ...

Background: Thyroid function in preterm infants is often altered for various reasons. LBW or VLBW newborns frequently present a particular form of congenital hypothyroidism (CH) characterized by low FT4 and delayed TSH elevation. The incidence of this disease is 1:250 for VLBW babies and 1:1589 for LBW newborns. In this condition, neonatal screening based solely on TSH can miss the diagnosis, therefore some screening programs have proposed to repeat the screening te...

Protein arginine methyltransferase 7 (PRMT7), a member of a family of enzymes that catalyse the transfer of methyl groups from S-adenosyl-L-methionine to nitrogen atoms on arginine residues, is involved in multiple biological processes, such as signal transduction, mRNA splicing, transcriptional control, DNA repair, and protein translocation. Currently, 12 patients with homozygous/compound heterozygous mutations in PRMT7 gene have been described defining the ...

Background: Disorders of sex development (DSD) are often due to disruption of the genetic programs that regulate gonad development. Some genes have been identified in these developmental pathways such as DAX-1, SOX-9, GATA-4 and others. The GATA-4 gene, located on chromosome 8p23.1, encodes GATA-binding protein 4 (GATA-4), a transcription factor that is essential for cardiac and gonadal development and sexual differentiation. Congenital heart disease (CHD) and...

Background: Maternal autoimmune hypothyroidism can have negative consequences on the fetus: on the one hand, maternal hypothyrosinemia might affect the fetal brain development in the early stages of pregnancy; on the other, thyroid inhibiting antibodies can pass through the placenta. It is currently unclear if these antibodies may affect the newborn’s thyroid function. Consequently, there are no certain indications regarding the management of newborns bor...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...
