The third exon of the endogenous RpS23 locus has been replaced with a version that encodes a R67K amino acid substitution. The same amino acid substitution has been identified in the orthologous human RPS23 gene in a patient with growth retardation and mild autism. In addition, the third exon is flanked by loxP sites (a Disc\RFPmCherry.3xP3 marker is also present within this loxP cassette, downstream of the RpS23 coding sequence). An attP site is also present within the second intron, upstream of the first loxP site of the cassette.

R67K
Analogous R67K mutation in human RPS23 implicated in brachycephaly, trichomegaly, and developmental delay; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change - one of two possible codons chosen arbitrarily.
RpS23R67K heterozygosity leads to a Minute phenotype: adults exhibit shorter scutellar bristles; larvae are developmentally delayed. Adults also show a small wing. imaginal discs exhibit increased apoptosis and an increased number of autophagosomes,
RpS23R67K/+ clones in mosaic imaginal discs are out-competed by neighboring wild-type cells, with increased apoptosis. Conditional heterozygosity for RpS26cKO in the imaginal disc anterior region leads to lysosomes accumulation only in the heterozygous region.
