GG (starting at nucleotide position 16682) is deleted. This results in a frameshift after amino acid residue G2482, producing a truncated protein containing 2482 N residues followed by an additional 46 amino acid residues.
adult thorax & microchaeta
Heterozygotes show loss of thoracic microchaetae. Homozygous adult NMcd3 escapers lack 63% of thoracic microchaetae. The remaining microchaetae are evenly spaced.
