Amino acid residues 284-287 are deleted.
The 13bp deletion creates a frameshift that truncates approximately half of the protein.

lethal - all die before end of larval stage (with Df(3R)3-4)
some die during third instar larval stage (with Df(3R)3-4)
embryonic/larval brain

polytene chromosome
hdγ2/Df(3R)3-4 mutants have small brains that display severely reduced levels of DNA synthesis compared to wild type. They also have no identifiable imaginal discs and small, under-replicated polytene chromosomes in the salivary glands.
