The annotation of Galphaq1 is incorrect. I genotyped Galphaq1 using PCR and found the point mutation should be G12617455A ("gCTACTTGAGCGATCTAGCT" to "aCTACTTGAGCGATCTAGCT"), instead of G12617071 that is annotated in FlyBase. Based on the location of the point mutation, it should disrupt the splice acceptor site of Galphaq RD and RJ isoforms.
