The key focal points of the MGVHB axis that may be affected by the gene variants are discussed in the “A Genetic Link Between Prematurity and Autism?” section and summarized below: EBF1 promotes differentiation of several neuronal cell types including the Purkinje cells [98] whose deficit has been implicated in autistic pathology [93] and has been also reported in premature infants [73]. This evidence concerns the gene EBF1 and autism.
