Remarks

Maternal Grandfather; subsequent to the submission of this sample and the establishment of the cell line, a detailed analysis of HapMap data has shown that the sample is from an unreported relative of another member or members of this panel, as described in Nature 437:1299-1320 (2005). (See Supplementary Table 15 and Supplementary Information on p.12. [PMID: 16255080]); donor subject has a single bp (G-to-A) transition at nucleotide 681 in exon 5 of the CYP2C19 gene (CYP2C19*2) which creates an aberrant splice site. The change altered the reading frame of the mRNA starting with amino acid 215 and produced a premature stop codon 20 amino acids downstream, resulting in a truncated, nonfunctional protein. Because of the aberrant splice site, a 40-bp deletion occurred at the beginning of exon 5 (from bp 643 to bp 682), resulting in deletion of amino acids 215 to 227. The truncated protein had 234 amino acids and would be catalytically inactive because it lacked the heme-binding region.
