Thirty-three genetic variations including fourteen novel ones were found in the SLC22A2 gene from 116 Japanese individuals. The novel variations were as follows: 596C>T (MPJ6_OC2003), 602C>T (MPJ6_OC2004), IVS5+20A>G (MPJ6_OC2010), IVS5-84_-83insG (MPJ6_OC2013), IVS6+30T>C (MPJ6_OC2014), IVS6+146G>T (MPJ6_OC2016), IVS6+179G>T (MPJ6_OC2017), IVS6-16delT (MPJ6_OC2018), 1920G>A (MPJ6_OC2022), 2153G>A (MPJ6_OC2026), 2157C>T (MPJ6_OC2028), 2306T>C (MPJ6_OC2031), 2342+5T>C (the last nucleotide number of mRNA+the position in the 3'-flanking region; MPJ6_OC2032) and 2342+127T>C (MPJ6_OC2033). Six variations were located in the exons, four of which were in the 3'-untranslated region (3'-UTR) of exon 11; six were in the introns; and two were in the 3'-flanking region. The frequencies were 0.802 for IVS5-84_-83insG, 0.013 for 602C>T, 0.009 for 596C>T, and 0.004 for the other 11 variations. Among them, 596C>T and 602C>T resulted in amino acid substitutions (Thr199Ile and Thr201Met, respectively).

UI MeSH Term Description Entries
D007438 Introns Sequences of DNA in the genes that are located between the EXONS. They are transcribed along with the exons but are removed from the primary gene transcript by RNA SPLICING to leave mature RNA. Some introns code for separate genes. Intervening Sequences,Sequences, Intervening,Intervening Sequence,Intron,Sequence, Intervening
D005091 Exons The parts of a transcript of a split GENE remaining after the INTRONS are removed. They are spliced together to become a MESSENGER RNA or other functional RNA. Mini-Exon,Exon,Mini Exon,Mini-Exons
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000075102 Organic Cation Transporter 2 Organic cation transporter consisting of twelve transmembrane domains and expressed primarily in the kidney. It transports a wide range of metabolites, drugs, and neurotransmitters from the blood to the KIDNEY TUBULES, including DOPAMINE; SEROTONIN; CHOLINE; and CISPLATIN.

D019943 Amino Acid Substitution The naturally occurring or experimentally induced replacement of one or more AMINO ACIDS in a protein with another. If a functionally equivalent amino acid is substituted, the protein may retain wild-type activity. Substitution may also diminish, enhance, or eliminate protein function. Experimentally induced substitution is often used to study enzyme activities and binding site properties. Amino Acid Substitutions,Substitution, Amino Acid,Substitutions, Amino Acid
