In addition, mutations in various members of the spectrin gene family are associated with erythroid cell disorders (SPTA1, SPTB) and neurological disorders (SPTAN1, SPTBN1, SPTBN2, and SPTBN4); however, no human genotype-phenotype correlation has been established for SPTBN5 to date (Rosenfeld et al., 2021). The gene discussed is SPTBN1; the disease is nervous system disorder.
