Introduction: Epidemiological data indicate that children born prematurely have a risk 3–5 fold higher of congenital hypothyroidism (CH). In addition premature infants born small for gestational age (SGA) have a risk of 12% higher to develop IC compared to prematures with appropriate development (AGA). The mechanisms that justify the increased risk of IC are still unknown. Some studies report a pattern of aberrant methylation associated with prematurity, intrauterine feta...

Premature ovarian failure (POF) is a common cause of female infertility affecting about 1–2% of women under the age of 40. This heterogeneous disorder is characterized by primary or secondary amenorrhea and elevated gonadotropin values. Several defects can cause POF, including autoimmunity, X chromosome abnormalities and gene mutations, but its pathogenesis is still unknown in the vast majority of women with normal karyotype. We recently described two sisters affected wit...

APECED is an autosomal – recessive syndrome defined by two of the following conditions: chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) or Addison disease (AD). Other autoimmune endocrine or non-endocrine conditions may be associated, like thyroiditis, celiac disease, alopecia and nail dystrophy. APECED is caused by mutations in the AIRE gene, mapping to 21q22.3. We report here 4 cases with atypical or incomplete presentation, that have been geneti...
