Core Tip
Core Tip: In familial hemophagocytic lymphohistiocytosis (FHL), the perforin (PRF1): c.163C>T mutation is rare and the clinical features have not been reported. We discuss a case of adult onset type 2 FHL with PRF1 c.65delC/c.163C>T compound heterozygous mutations, and conduct a predictive analysis of the effects of the two mutations on PRF1 function and disease onset.
