개연성 돌리칠 피로인산염 Glc1Man9GlcNAc2 알파-1,3-glucosyl transferase는 인간에서 ALG8 유전자 에 의해 암호화된 효소 다.[5]
이 유전자는 ALG6/ALG8 글루코실트전달효소 계열의 한 구성원을 인코딩한다. 인코딩된 단백질은 단백질의 N연계 글리코실화를 위해 지질연계 올리고당 전구체에 두 번째 포도당 잔류물을 추가하는 촉매 작용을 한다. 이 유전자의 돌연변이는 글리코실레이션 타입 Ih(CDG-Ih)의 선천성 질환과 관련이 있다. 대안으로 서로 다른 ISO 양식을 인코딩하는 분할된 대본 변형이 식별되었다.[5]
