Two novel mutations of the glycine receptor gene in a Taiwanese hyperekplexia family

The authors report a Taiwanese family with autosomal recessive hyperekplexia. Two novel mutations, W96C (from the paternal allele) and R344X (from the maternal allele), which are located in exon 4 and exon 7 of the GLRA1 gene, were identified in this family. A series of electrophysiologic investigations were conducted in one of the probands, and the results suggest that the "startle center" is located subcortically.
