Homozygous mutations in HAX1 cause an autosomal recessive form of severe congenital neutropenia (CN). By screening 88 patients with CN, we identified 6 additional patients with HAX1 mutations carrying 4 novel mutations. Of these, 2 affect both published transcript variants of HAX1; the other 2 mutations affect only transcript variant 1. Analysis of the patients' genotypes and phenotypes revealed a striking correlation: Mutations affecting transcript variant 1 only were associated with CN (23 of 23 patients), whereas mutations affecting both transcript variants caused CN and neurologic symptoms, including epilepsy and neurodevelopmental delay (6 of 6 patients). In contrast to peripheral blood, transcript variant 2 was markedly expressed in human brain tissue. The clinical phenotype of HAX1 deficiency appears to depend on the localization of the mutation and their influence on the transcript variants. Therefore, our findings suggest that HAX1 isoforms may play a distinctive role in the neuronal system.
