SYT2

Synaptotagmins, like SYT2, are integral membrane proteins of synaptic vesicles thought to serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis (Hilbush and Morgan, 1994 [PubMed 8058779]).[supplied by OMIM

synaptotagmin II

Exhibits calcium-dependent phospholipid and inositol polyphosphate binding properties (By similarity).
May have a regulatory role in the membrane interactions during trafficking of synaptic vesicles at the active zone of the synapse (By similarity).
Plays a role in dendrite formation by melanocytes (PubMed:23999003).

Myasthenic syndrome, congenital, 7A, presynaptic, and distal motor neuropathy, autosomal dominant (CMS7A):
A form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre-synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features are easy fatigability and muscle weakness. CMS7A is an autosomal dominant, presynaptic disorder resembling Lambert-Eaton myasthenic syndrome. Affected individuals have a variable degree of proximal and distal limb weakness, muscle fatigue that improves with rest, mild gait difficulties, and reduced or absent deep tendon reflexes.
Myasthenic syndrome, congenital, 7B, presynaptic, autosomal recessive (CMS7B):
An autosomal recessive form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre-synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features are easy fatigability and muscle weakness. CMS7B is characterized by defects at the pre-synaptic neuromuscular junction and severe generalized muscle weakness apparent from birth. Decreased fetal movements may be apparent in utero. Affected infants have generalized hypotonia, head lag, and facial muscle weakness with ptosis. Some patients may have respiratory involvement.
