Disease Associations  (1) Diseases Associated with Human STXBP1
Mutations,
alleles, and
phenotypes
All mutations/alleles(8) : Gene trapped(3) Targeted(5)
Incidental mutations (data from Mutagenetix , APF )
 
Mice homozygous for a targeted null allele show an apparently normal initial brain assembly but lack synaptic neurotransmitter release, display massive neuron apoptosis and degeneration after assembly of the neuronal networks, and die shortly after birth probably due to an inability to breathe.
