Contains a G to A conversion in the splice donor site of exon IV in pntP2.
Nucleotide substitution: G?A.
G23312886A
G?A
Mutation is in splice donor site. Position of mutation described in FBrf0160371 on reference sequence inferred by FlyBase curator based on sequence in FBrf0058076 Figure 5.
Mutant embryos have ectopic cardioblasts that form enlarged hearts comprising disorganised rows of cardioblasts. The ectopic cardioblasts appear to be restricted to the posterior domain.
Analysis of excess cardioblast phenotype provides an allelic series:pntS012309, pnt2 > pntRR112, pntrM254 > pntΔ88, pnt07825.
