Juhua Ji et al. [21] identified compound heterozygous variants in NBAS genes c.939_939delGC (p.Arg313Profs*13) and p.Cys448Arg in a patient with recurrent fever-triggered liver failure, normal serum immunoglobulin profile, and increased cytotoxic CD8+ cells but normal CD19+ B cells. This evidence concerns the gene NBAS and liver failure.
