The neuron-specific RNA binding protein Hu Antigen D (HuD) (also known as Embryonic Lethal, Abnormal Vision, Drosophila Like RNA Binding Protein 4 (ELAVL4)) is overexpressed in a number of cancer types, notably NB and small cell lung cancer [2–4]. The gene discussed is ELAVL4; the disease is embryonic lethality.
