Re-integration of sequence using the attP site present in TI{TI}CG4743KO (after first removing the loxP cassette), reconstituting a mutant CG4743 transcription unit at the native locus; contains a R166Q amino acid substitution (this mutation is equivalent to a variant with clinical significance in the orthologous human gene). In addition, a loxP cassette containing a wGMR.PHb marker has been inserted downstream of the CG4743 coding sequence and the attP site has been converted into an attR site (this is located upstream of the CG4743 coding sequence).
Disease model in flies has not been developed.
