Background: The decreased immune tolerance caused by mutations of the autoimmune regulatory gene (AIRE) lead to a spectrum of variable organ specific autoimmune disorders known as autoimmune polyglandular syndrome type 1 (APS-1). The rarity of the syndrome and the heterogenous clinical manifestations at the onset of the disease may delay the diagnosis. Only when two major components of the triad chronic mucocutaneous candidiasis – hypoparathyroidism &nda...

Introduction: Hypophosphatasia (HPP) is a rare, potentially fatal, either autosomal dominant or recessive genetic disorder caused by the loss of function of the tissue-non-specific isoenzyme of the serum alkaline phosphatase, due to pathogenic variants of the ALPL gene. The onset of the deleterious effects on bone metabolism is highly variable, ranging from mild cases with dental abnormalities to severe forms that can be life-threatening in infancy or early ch...
