IRIS PubliCatt
PubliCatt è il repository istituzionale ad accesso aperto dell'Università Cattolica del Sacro Cuore, dove gli utenti autorizzati afferenti all'Ateneo provvedono direttamente e autonomamente a depositare e a rendere visibili le proprie pubblicazioni, inserendo i dati descrittivi del documento stesso ("metadati", quali il titolo, autore, abstract, etc.) e, laddove possibile, il testo della pubblicazione stessa (full-text).
PubliCatt utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da CINECA.
EnglishWe describe the third family in the world, after Arabian and Turkish ones, displaying an autosomal recessive autoimmune disease (AID), mimicking systemic lupus erythematosus (SLE), with unusual manifestations due to a homozygous frame-shift variant in DNASE1L3. SLE is a complex AID characterized by multiple organ involvement. Genetic risk variants identified account for only 15% of SLE heritability. Rare Mendelian forms have been reported, including DNASE1L3-related SLE. Through specific genetic tests we identified a homozygous 2 bp-deletion c.289_290delAC (NM_004944.2) in DNASE1L3, predicting frameshift and premature truncation (p.Thr97Ilefs*2). The same mutation was previously reported in three sisters, born from consanguineous parents and affected with hypocomplementemic urticarial vasculitis syndrome (HUVS). As approximately 50% of individuals affected with HUVS develop SLE, it is still unclear whether it is a SLE sub-phenotype or a separate condition. Lupus (2016) 0, 1–5.

| Abstract: | We describe the third family in the world, after Arabian and Turkish ones, displaying an autosomal recessive autoimmune disease (AID), mimicking systemic lupus erythematosus (SLE), with unusual manifestations due to a homozygous frame-shift variant in DNASE1L3. SLE is a complex AID characterized by multiple organ involvement. Genetic risk variants identified account for only 15% of SLE heritability. Rare Mendelian forms have been reported, including DNASE1L3-related SLE. Through specific genetic tests we identified a homozygous 2 bp-deletion c.289_290delAC (NM_004944.2) in DNASE1L3, predicting frameshift and premature truncation (p.Thr97Ilefs*2).
