In the following years, further CJD cases have been reported to be associated with administration of contaminated corneal grafts and EEG recordings with deep needle electrodes [16,17,18], while in the mid-1980s hGH and hDM grafts were identified as exposure sources responsible for iCJD occurrence [19,20,21,22]. The gene discussed is GH1; the disease is Creutzfeldt Jacob disease.
