2R:18,281,323..18,281,323 [-]
Nucleotide change:

C18281323T

Amino acid change:

Q1920term | sbb-PD; Q1930term | sbb-PG; Q1920term | sbb-PH; Q1930term | sbb-PJ

Reported amino acid change:

Q1899term

Comment:

Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change. There is no Gln at position 1899 in the reference sequence so the mutation was mapped to position 1898. There are multiple Gln residues in the region.
