Seven novel single nucleotide polymorphisms in the human SLC22A1 gene encoding organic cation transporter 1 (OCT1).

Abstract：

:Twenty genetic variations, including seven novel ones, were found in the human SLC22A1 gene, which encodes organic cation transporter 1, from 116 Japanese individuals. The novel variations were as follows: -94C>A in the 5'-untranslated region (A of the translation start codon is numbered +1 in the cDNA sequence; MPJ6_OC1001), 350C>T (MPJ6_OC1004), IVS1-35T>C (MPJ6_OC1006), 561G>A (MPJ6_OC1010), IVS6+75C>G (MPJ6_OC1014), IVS8+108A>G (MPJ6_OC1017), and 1671_1673delATG (MPJ6_OC1020). The frequencies were 0.082 for IVS1-35T>C, 0.022 for IVS6+75C>G, 0.009 for 561G>A, and 0.004 for the other 4 variations. Among them, 350C>T resulted in the amino acid substitution Pro117Leu, which is located in the large extracellular loop between transmembrane domains 1 and 2. Also, we detected the four previously reported nonsynonymous variations, 123C>G (Phe41Leu), 480C>G (Phe160Leu), 1022C>T (Pro341Leu), and 1222A>G (Met408Val) with frequencies of 0.004, 0.086, 0.168, and 0.810, respectively.
