Abstract
A nonconservative amino acid substitution (Ser857Asn) in the human delayed-rectifier potassium channel DRK1 (KCNB1 locus), a candidate gene for the low voltage alpha electroencephalogram (EEG) trait locus (LVEEG1) at 20q13.2, and its frequency in ethnic population samples are described. The frequency of Asn857 in seven different ethnic population samples, totalling more than 1600 individuals, ranged from zero to greater than 3%. However, no association was found between Asn857 and the low voltage alpha EEG trait (LVA) in a population of 105 subjects assessed for the EEG, 24 of whom actually had LVA.
