Nature of Mutation
DNA sequencing using the SOLiD technique identified an A to G transition at position 958 of the Ugt2a3 transcript. The mutated nucleotide causes a leucine to glutamine substitution at amino acid 309 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Ugt2a3 gene encodes a 534 amino acid single-pass type I transmembrane UDP-glucuronosyltransferase, which catalyzes phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. UDP-glucuronosyltransferases are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds (Uniprot Q8BWQ1).
 
The L309Q change occurs in the extracellular domain, and is predicted to be probably damaging by the PolyPhen program.
