Congenital myasthenic syndrome 11 is caused by genetic changes that affect the communication between nerves and muscles, leading to muscle weakness. These genetic changes are typically inherited from one or both parents, who may not show any symptoms themselves. Risk factors include having a family history of the condition, as it is passed down through families. The specific genetic mutations involved can vary, but they all disrupt the normal function of proteins essential for muscle contraction. Environmental factors do not play a significant role in the development of this syndrome.

Factores de Riesgo Genéticos

Congenital myasthenic syndrome 11 is primarily caused by genetic mutations that affect the communication between nerve cells and muscles. These mutations disrupt the normal function of proteins that are essential for muscle contraction. The genetic risk factors are specific mutations in certain genes that are inherited in an autosomal recessive manner.

• COLQ gene mutation: Mutations in the COLQ gene can lead to a deficiency in a protein that anchors acetylcholinesterase in the synaptic cleft. This deficiency impairs the breakdown of acetylcholine, a neurotransmitter, resulting in prolonged muscle contraction and weakness. The COLQ gene mutation is inherited in an autosomal recessive pattern, meaning both copies of the gene in each cell have mutations.

• CHAT gene mutation: The CHAT gene provides instructions for making an enzyme called choline acetyltransferase, which is crucial for producing acetylcholine. Mutations in this gene can reduce the production of acetylcholine, leading to impaired muscle function. Like other genetic risk factors for this syndrome, CHAT gene mutations are inherited in an autosomal recessive manner.

• RAPSN gene mutation: RAPSN gene mutations affect the rapsyn protein, which is important for clustering acetylcholine receptors at the neuromuscular junction. These mutations can lead to a reduced number of functional receptors, causing muscle weakness. The inheritance pattern is autosomal recessive, requiring mutations in both gene copies for the condition to manifest.

• DOK7 gene mutation: Mutations in the DOK7 gene disrupt the function of a protein involved in the development and maintenance of the neuromuscular junction. This disruption can lead to a decrease in the number of acetylcholine receptors, affecting muscle strength. DOK7 gene mutations are also inherited in an autosomal recessive pattern.
