The deletion of 10q26 includes the EBF3 gene, of which low expression has been linked to hypotonia, ataxia, and delayed development syndrome (OMIM 617330), resulting in various congenital abnormalities, including microcephaly, growth retardation, intellectual disability, craniofacial dysmorphism, micropenis, cryptorchidism, etc. [34–37]. This evidence concerns the gene EBF3 and microcephaly.
