MYD88 variant was identified through T-NGS in a patient with atypical features of MyD88 deficiency, presenting with chronic yersiniosis. PLDN variant was identified through WES in a patient with incomplete features of Hermansky–Pudlak type II syndrome and impairment of NK cytolytic activity. DOCK8/CLEC7A variants were identified for the first time in a patient with intractable diarrhea, malignancy, and features of Hyper IgE syndrome.
