IMPORTANCE: Mutations in the CERC1 gene associated with deficiency in the ADA2 protein (DADA2) have been implicated in the pathogenesis of cutaneous polyarteritis nodosa (cPAN) and early-onset vasculopathy. DADA2 is not only limited to cPAN and vasculopathy but also includes immunodeficiency that affects several cellular compartments, including B cells; however, some patients appear to have a more indolent, skin-limited disease.
OBSERVATIONS: In this report, we describe 2 white siblings (female and male) with a history of cPAN with DADA2 as a result of novel compound heterozygous mutations inherited in trans in the CECR1 gene (c.37_39del [p.K13del] and c.1159C>A [p.N328K]). The onset of disease was earlier in the female sibling than the male sibling although both were diagnosed as having cPAN in early childhood. The disease is associated with a more significant immunodeficiency and other systemic symptoms in the female than the male sibling.
CONCLUSIONS AND RELEVANCE: These findings suggest a genetic cause of cPAN in some patients. Therefore, DADA2 should be considered in patients with cPAN, specifically in those whose conditions are diagnosed at an early age, regardless of their ethnicity, presence or absence of systemic symptoms, or a family history of the disease.
