Added comment: Female infant of Chinese ancestry, presented at 2 years of age with whole-body rash with histological features of hyperkeratosis, parakeratosis and acanthosis with elongated rete ridges, focal liquefaction and degeneration of the basal layers of epidermis, vascular proliferation in the superficial dermis, infiltration of lymphocytes and eosinophils around small blood vessels in the dermis. She has recurrent infections (frequent and severe pneumonia).
Extensive functional validation demonstrating heterozygous de novo mutation (p.T132A) impairs REXO2’s ability to cleave RNA leading to activation of the dsRNA sensor MDA5 leading to a Type 1 interferonopathy.
