Concentrations of BAMBI in CSF were not statistically different between CJD cases harbouring methionine/methionine [MM] (1750 ± 632 pg/mL, n = 11), methionine/valine [MV] (1833 ± 506 pg/mL, n = 7) and valine/valine [VV] (1672 ± 624 pg/mL, n = 11) at codon 129 of the PRNP gene (p > 0.05). The gene discussed is PRNP; the disease is Creutzfeldt Jacob disease.
