Scientific BioThings ID Mapping

BioThings API スイート (MyGene, MyVariant, MyChem) を活用した 多データベース横断の ID 変換・アノテーション取得パイプラインを提供する。

When to Use

• 遺伝子 ID 間の変換 (Entrez ↔ Ensembl ↔ Symbol ↔ UniProt) を行うとき
• 変異 ID のアノテーション (ClinVar, dbSNP, CADD 等) を取得するとき
• 化合物 ID の変換 (DrugBank ↔ ChEMBL ↔ InChIKey ↔ PubChem) を行うとき
• バッチクエリで多数の ID を一括アノテーションするとき
• 複数データベースのメタ情報を統合するとき
