Position of mutation on reference sequence inferred by FlyBase curator. Mutation is in splice donor site. Predicted to disrupt splicing after exon 10 (FlyBase curator inference based on sequence in Figure 7 of FBrf0174713).
Nucleotide substitution: G?A. G to A transition in the first base of the intron following exon 4, disrupting the conserved GT dinucleotide in the 5' splice site consensus sequence. Predicted to disrupt splicing.
