i6059004 in 23andMe (chromosome and position comparison). Also known as the N124S mutation (asn124-to-ser) in its gene, KLKB1. I believe the risk allele is G for Prekallikrein Deficiency if I'm reading the OMIM entry, but that it only has an effect if it's homozygous. I may be reading this incorrectly. It's 229000.0005, which will redirect you to 229000.0004.
