Something seems wrong between dbSNP and the results from 23andMe and FTDNA. See Talk:Rs4148323 for more information.
rs4148323, a SNP also known as 211G>A or G71R, occurs in the UGT1A1 gene, and defines the UGT1A1*6 allele. This allele is associated with Gilbert's syndrome among Asians, Crigler-Najjar syndrome type II (CN-II), and transient familial neonatal hyperbilirubinemia.
