To the Editor:

We report two novel heterozygous point mutations, S32R and S32N, in the NFKBIA gene encoding IκBα in two Japanese patients with severe clinical phenotypes of an autosomal dominant (AD) form of anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID).

Patient 1 (P1) was born from non-consanguineous healthy Japanese parents after an uncomplicated pregnancy. He was transferred to a hospital because of persistent skin rash soon after birth. Although he was healthy and had no signs of infection, respiratory failure and seizure occurred at the age of 2 months. Since immunodeficiency was suspected from the results of laboratory data, he was referred to our hospital. Routine laboratory evaluation demonstrated persistent elevation of C-reactive protein (CRP), high white blood cell (WBC) counts with lymphocytosis, and low immunogloblin levels. He showed multiple erythemas with scales on the face and limbs and had oral candidiasis (Fig. E1). He had symptoms of conical teeth...
