Description
酵素は、代謝プロセス時にひとつの分子の別の分子への転換を触媒するので、これらは代謝において重要な役割を果たす。代謝酵素に欠陥があるか又は個体において異常な量存在する場合、代謝障害が生じ得る。代謝障害は、酵素の非存在もしくは過剰生成又は欠陥のある酵素の生成につながる遺伝形質に起因することが多い。
従って、個体における代謝障害を効率的に診断する方法の必要性が存在する。本発明は、この必要性を満足し、更に関連した利点を提供する。
本発明は、単独の試料から1種又は複数の代謝障害の少なくとも2種のマーカー又は指標を検出することに関連している。少なくとも1種の指標は、試料中の代謝の指標となる酵素の活性に対応し、及び少なくとも1種の指標は、試料中に内在性に含まれた代謝被検体の存在及び量に対応している。先行する質量分析を使用する遺伝子スクリーニングの臨床的方法は、単に単独の試料中の代謝被検体を検出した。特にChace(米国特許第6,258,605号及び第6,455,321号明細書)は、分析前のメタノール抽出により患者試料(乾燥血液スポット)を調製することを開示している。このような条件下で、酵素は失活され、その結果、酵素活性の測定は、実行不可能であり、更には企図されない。
代謝障害の検出は、代謝障害の易罹患性の診断又は予測に使用することができ、その理由は、この障害の生理的又は行動的症状が顕在化し始めているかどうかに関わりなく、本発明の方法を用いて試験される生化学的インジケーターは、代謝障害の指標であるからである。
フェニルケトン尿症(PKU)は、フェニルアラニンがチロシンに転換されない、芳香族アミノ酸代謝の障害である。PKUは、治療されないと、様々な程度の精神遅滞につながる。高フェニルアラニン血症は、精神遅滞及び筋肉硬直につながる。ホモシスチン尿症は、血管閉塞疾患、骨粗鬆症、ホモシスチン及びメチオニンの蓄積、並びに様々な発達遅延につながる。カエデシロップ尿症(MSUD)は、分枝鎖アミノ酸の代謝の障害により引き起こされ、血中のロイシン、イソロイシン及びバリンの上昇したレベルを生じる。治療されない場合、嗜眠の昏睡への進行、発達遅延、及び痙攣が発生するであろう。I型チロシン血症(遺伝性チロシン血症)は、急性肝不全又は慢性肝硬変及び肝細胞癌につながる。シトルリン血症は、痙攣、食欲不振、吐気及び嗜眠、その後速やかに致命的可能性のある昏睡につながる。
本願明細書において使用される用語「代謝被検体」は、代謝障害を経験している個体の、代謝障害を経験していない個体と比べた体内の量、活性、又は生理的特徴が変更された物質を意味する。代謝被検体の例は、アミノ酸、脂肪酸及び有機酸、並びに他の小型分子、更には巨大分子、例えば核酸、ポリペプチド又は炭水化物などを含む。
必要ではないが、この被験試料は、代謝被検体、酵素生成物及び/又は参照物質の量の検出を増強するために、質量分析前に誘導体化することができる。周知の誘導体化法の例は、試料の酸及びブタノールとの反応である。
本発明の方法は、1種又は複数の代謝の指標となる酵素の、対応する基質に作用する能力を阻害する試薬の使用に関する。本願明細書において使用される用語「阻害」は、生成物の形成が検出不能又は有意でないように、酵素活性を低下又は阻止することを意味する。
括弧内又はその他で先に示された全ての雑誌記事、参考文献、及び特許の引用は、先に言及されたかどうかに関わりなく、本願明細書に参照として組入れられている。
本発明の様々な態様の機能に実質的に影響を及ぼさない修飾も、本願明細書に記された発明の定義に含まれることが理解される。従って下記実施例は、本発明を例証することを意図し、限定するものではない。
本実施例は、患者試料由来の代謝被検体及び代謝の指標となる酵素生成物の量の同時決定を説明する。
酵素ビオチニダーゼは、ビオチニダーゼ欠損症と称される代謝障害の公知の代謝の指標となる酵素である。治療されない状態において、新生児の深刻な、ビオチニダーゼ欠損症は典型的には過換気、咽頭喘鳴及び無呼吸を随伴することが多い、痙攣、低血圧、及び発疹のような、神経学的及び皮膚-関連した症状により特徴付けられる。年長の小児も、脱毛、運動失調、発達遅延、神経感覚性聴覚障害、視神経萎縮、及び再発性感染症を有することがある。部分的ビオチニダーゼ欠損症の個人は、特にストレス時に、低血圧、皮膚発疹、及び脱毛を有することがある。一旦検出されると、ビオチニダーゼ欠損症はしばしば、ビオチン投与により治療可能である。
紙の上の乾燥血液試料は各々、マイクロウェルプレートのウェルへパンチ孔をあけた。各試料は同位体標識したビオシチン(ビオチニダーゼの基質)を含有する緩衝液50μlで再構成し、この混合物を、42℃で17時間インキュベーションした。次にα-アミノ酸及びアシルカルニチンの、並びにビオチニダーゼ反応の生成物の同位体標識した内部標準を含有するメタノール140μlを添加し、このプレートを27℃で30分間振盪した。このプレートを次に、アルミフォイルで覆い、自動試料採取装置上に配置した。各処理した試料は、タンデム質量分析により分析し、ビオチニダーゼ生成物、内在性α-アミノ酸及び内在性アシルカルニチンの濃度を、内部標準を基に定量した。
