Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; also called APS-1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is characterized by two of the three major clinical symptoms that may be present: Addison’s disease, and/or hypoparathyroidism and/or chronic mucocutaneous candidiasis.(More)
CONTEXT Autoimmune polyendocrine syndrome type 1 (APS1) is a childhood-onset monogenic disorder caused by mutations in the autoimmune regulator (AIRE) gene, including the distinctive R139X in Sardinia. Its rarity and great variability in manifestations/onset ages make early diagnosis difficult. To date, very few longitudinal studies of APS1 patients have(More)
Programs of prospective carrier screening and genetic counseling for beta-thalassemia among couples planning marriage, preconception, or during early pregnancy are ongoing in several at-risk populations in the Mediterranean area, including Greeks, Greek Cypriots and Continental Italians. Carrier detection is carried out by haematological analysis followed(More)
In this study, we have carried out molecular analysis of the AIRE (autoimmune regulator) gene in 11 patients (from 8 families) affected by autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy, originating from a restricted area of Southern Italy (the Salento peninsula in Puglia). Of the 16 mutant AIRE alleles from the 8 probands studied, 12(More)
Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by degeneration of the anterior horn cells of the spinal cord, causing symmetric proximal muscle weakness. SMA is classified in three clinical types, SMA I, SMA II, and SMA III, based on the severity of the symptoms and the age of onset. About 95% of SMA cases are caused by(More)
We report two novel mutations, c.230T>C (p.F77S) and c.64_69del (p.V22_D23del) within the HSR domain of the AIRE protein in two patients of Italian descent affected by APECED. Both mutations were found in the compound heterozygous state respectively with c.994+5G>T and c.232T>A (p.W78R). With the two-hybrid assay in the yeast system we found that constructs(More)
Autoimmune endocrinopathies are characterised by an increased number of peripheral blood lymphocytes (PBL) expressing activation/ memory markers on their surface. The aim of this study was to determine whether a similar finding could be detected in a group of 11 paediatric and young adult patients suffering from autoimmune polyglandular syndrome type 1(More)
Thalassemias are common autosomal recessive disorders especially in populations of Mediterranean, Middle Eastern, and Far Eastern descent. Relatively high incidence is also observed in people of Asian Indian origin but the incidence is more limited in those of African descent. Beta Thalassemias are heterogeneous at the molecular level, with more than 150(More)
Vitamin D response elements (VDREs) have been found in the promoter region of the MS-associated allele HLA-DRB1*15:01, suggesting that with low vitamin D availability VDREs are incapable of inducing *15:01 expression allowing in early life autoreactive T-cells to escape central thymic deletion. The Italian island of Sardinia exhibits a very high frequency(More)
