Core Tip

Core Tip: We report the case of a newborn infant with familial hemophagocytic lymphohistiocytosis who had clinical manifestations by the age of 7 d. The genetic test revealed a compound heterozygous mutation of c.658G>C (p.Gly220Arg) and c.1066C>T (p.Arg356Trp). The two mutations carried by the index cases were not commonly seen variants in Chinese PRF1 mutations. The clinical manifestation of our case strongly suggests that c.658G>C (p.Gly220Arg) is also a pathogenic variant.
