These include 10 neurodevelopmental genes, namely AUTS2, ASTN2, COL25A1, GFRA1, MGAT5B, MTR, NFIB, PTPRD, ROBO1 and HERC2, a centrosomal protein gene associated with microcephaly (CDK5RAP2), two genes with possible associations with immunity (FCRL3 and THSD7B), a cell adhesion gene associated with epithelial tumorigenesis (PTPRK), and a nucleoside transporter (SLC28A3). The gene discussed is NFIB; the disease is microcephaly.
