NBAS and autoimmune hemolytic anemia: Based on the regions of NBAS protein the variants affect, NBAS-associated diseases can be classified into 3 clinical subgroups: β-propeller (combined ALF and multisystemic phenotype), Sec39 (mainly ALF) and C-terminal (predominant multisystemic phenotype).[4] Because this case has a heterozygote of c.6840G>A and c.335 + 1G>A, so it is supposed to involve both β-propeller and C-terminal of NBAS protein, which may explain the reason of development of AIHA along with other multisystemic symptoms.
