Complement component C1s

The C1S gene encodes the serine protease of the complement component C1 which activates C2 and C4 to form a C3 convertase the essential part of classical complement activation. Mutations cause autosomal recessive C1s deficiency or dominant periodontal Ehlers-Danlos syndrome.
