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). 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). 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. |
