We describe a case of adult onset familial HLH with a novel exon 19, c.1607G>T (p.Arg536Leu) heterozygous mutation of the UNC13D gene in a 40-year-old woman who developed HLH during her first and second pregnancies, both episodes occurring during the first trimester. Our patient was treated successfully both times with HLH-94 protocol following spontaneous abortions and is currently in the process of getting a bone marrow transplant. We also discuss pregnancy as a potential trigger for late onset familial HLH %K Hemophagocytic lymphohistiocytosis %K Pregnancy %K Familial %K Adult %K Mutation %K Chemotherapy %K Genetic %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6134992/
