Point mutation in the first zinc finger domain.
Nucleotide substitution: G996A. This causes a glu (conserved in GATA protein family) to lys substitution within a 23 amino acid stretch in the region of the N-terminal zinc finger.

Position of mutation on reference sequence inferred by FlyBase curator based on author statement. (Figure 3 and Table 1)
Homozygotes exhibit a dorsal hole. Heterozygotes exhibit a strong thoracic cleft defects and lack postverticals, inner verticals and some anterior orbitals, extra dorsocentral and scutellar bristles. Heterozygotes with pnrVX5 exhibit variegating position effect.
Heterozygotes display extra dorsocentral bristles. Dominant phenotype enhanced in viable transallelic combinations with pnrV1.
Class A allele. Allelic series for dominant phenotype, going from greatest to least effect pnrD4 > pnrD1 > pnrD2 = pnrD3.
Class 4 pnr allele: dominant allele causing a gain of bristles. Associated with Akt12.
