Aims of the present study are: 1) to report an additional Sicilian patient with autoimmune polyendocrinopathy-candidiasis-ectodermal-dystrophy (APECED), whose genotypic features are original, in that she is the first APECED patient with three coexisting mutations of Autoimmune Regulator (AIRE) gene, two of which had never been reported to date; 2) to review the genotypic epidemiology of APECED in Italy, in order to underline the great genetic heterogeneity of this disorder in Italian patients. Both the novel mutations of our new patient, named S107C and Q108fs respectively, were detected on exon 3 and were inherited by the mother, whereas the third one (T16M) was inherited by the father. Phenotypically, the present case is quite characteristic, in that she exhibited a classical clinical picture, with no original features. Conclusions: a) this is the seventh Sicilian APECED patient identified to date, and the first one with no R203X mutation; b) our data confirm that distribution of mutations may considerably vary according to different geographical distribution, within the same country, thus suggesting a potential founder effect.
► We underline the heterogeneity among APECED Italian patients.
► The genotypical pattern of southern Italian regions is very different.
► R203X is peculiar of Sicilian patients but other mutations may be found.
► The coexistence of three AIRE gene mutations represent a finding absolutely original.
