However, the frequency of this alteration in FHLH patients associated with PRF1 mutation is much higher than that observed in controls (26.2%, P = 0.0002), suggesting that the alteration is an important genetic susceptibility factor.

As both STX11 and UNC13D are involved in vesicle trafficking and membrane fusion, we conclude that, besides mutations in perforin 1, defects in the endocytotic or the exocytotic pathway may be a common mechanism in FHL.
