  • Official Full Name
  • Potassium Voltage-Gated Channel, KQT-Like Subfamily, Member 1
  • Background
  • The human KCNQ1 gene encodes the pore-forming subunit of Kv7.1, a voltage-gated potassium channel (also known as KvLQT1). Mutations in KCNQ1 cause an inherited form of long QT syndrome, type 1. KCNQ1 channels expressed in the heart are anti-targets in cardiac risk assessment.
