The present study describes a 19-year-old woman with systemic herpes simplex virus (HSV)-1 infection and hemophagocytic lymphohistiocytosis (HLH) postpartum, and a fatal course of neonatal herpesvirus infection. Functional investigation of cells from the mother demonstrated significantly impaired induction of antiviral interferons and cytokines in the context of normal activation of the transcription factors NF-κB and IRF3. Whole-exome sequencing did not reveal any functionally validated genetic variants. We suggest that the functionally impaired antiviral responses, potentially caused by a variant in CASP8 or other variants in noncoding regions of the genome, contributed to the unusually severe disease course observed in two generations.
