For cg06126421 located at the intergenic region of chromosome 6, we found an association between DNA methylation levels and the expression of the genes TUBB and MUC21. TUBB encodes a beta tubulin protein of the microtubule cytoskeleton and has shown to be involved in microcephaly with structural brain abnormalities in humans. Here, MUC21 is linked to microcephaly.
