Genomic Mutations involving Rapsn (2)
Incidental mutations (data from Mutagenetix , APF )
Homozygotes for a targeted null mutation exhibit absence of acetylcholine receptor clusters at end plate band of neuromuscular synapses, muscle weakness, and respiratory distress leading to lethality within hours of birth.
Rapsn interacts with 44 markers (Mir28b, Mir28c, Mir142, ...)
