Genes in the β- and δ-globin lineage are located to the right in the gene clusters and, if active, are expressed in fetal and/or adult erythroid cells. Genes in the ε-, γ-, and η-globin gene lineage are toward the left in the gene clusters and are expressed in embryonic erythroid cells, except for the γ-globin genes in anthropoid primates. Mar 13, · Many of the genes found to be associated with autism are involved in the function of the chemical connections between brain neurons (synapses).
