Summaries for Myasthenic Syndrome, Congenital, 23, Presynaptic

UniProtKB/Swiss-Prot : ⁷³ Myasthenic syndrome, congenital, 23, presynaptic: 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 include easy fatigability and muscle weakness. CMS23 inheritance is autosomal recessive.

MalaCards based summary : Myasthenic Syndrome, Congenital, 23, Presynaptic, is also known as cms23. An important gene associated with Myasthenic Syndrome, Congenital, 23, Presynaptic is SLC25A1 (Solute Carrier Family 25 Member 1). Related phenotypes are ptosis and easy fatigability
