Sequence Features

 13G -> R (in CMS4B; impaired association with alpha CHRNA1 subunit of AChR; dbSNP:rs372635387) VAR_021213 dbSNP
 18G -> V (in dbSNP:rs4790235) VAR_048170 dbSNP
 75W -> R (in CMS4B; strongly reduces agonist affinity and gating efficiency; dbSNP:rs193919341) VAR_071629 dbSNP
 98L -> P (in CMS4A; rare example of recessive inheritance; dbSNP:rs28929768) VAR_019567 dbSNP
 141P -> L (in CMS4B; marked decrease in rate of AChR channel opening; reduction in frequency of open channel state and resistance to desensitization by ACh; dbSNP:rs121909512) VAR_000289 dbSNP
 163S -> L (in CMS4B; fails to assemble with alpha CHRNA1 subunit of AChR; dbSNP:rs121909516) VAR_021214 dbSNP
 167R -> L (in CMS4C; significantly reduced AChR expression; dbSNP:rs121909514) VAR_000290 dbSNP
 241L -> F (in CMS4A; mild form with variable penetrance; dbSNP:rs28999110) VAR_019568 dbSNP
 265P -> L (in CMS4C; prolongs burst open duration 2- fold by slowing the rate of channel closing; dbSNP:rs759226183) VAR_000291 dbSNP
 284T -> P (in CMS4A; markedly prolonged channel openings in presence of agonist; as well as opening in the absence of agonist; dbSNP:rs121909510) VAR_000292 dbSNP
 285V -> A (in CMS4A; slow-channel mutation; increases gating equilibrium constant by 25-fold, owing to increased opening rate and decreased closing rate; no effect on the choline dissociation rate constant) VAR_077364
 289L -> F (in CMS4A; slows rate of AChR channel closure and increases apparent affinity for ACh; causes pathologic channel openings even in the absence of ACh resulting in a leaky channel; dbSNP:rs121909511) VAR_000293 dbSNP
 331R -> W (in CMS4C; shortens burst duration 2-fold by slowing the rate of channel opening and speeding the rate of ACh dissociation; has a mild fast-channel kinetic effect on the AChR by shortening the long burst and increasing the decay of the endplate current; dbSNP:rs121909515) VAR_000294 dbSNP
 431A -> P (in CMS4B; causes an increase in distributions of rates for channel opening and closing increasing the range of activation kinetics; dbSNP:rs121909517) VAR_021215 dbSNP
