Drosophila genotypes: dNRXN3 LOF allele (y1 w*; Mi{y+mDint2=MIC}nrx-1MI02579or nrx-1LOF, BDSC: 61696), dNRXN3 RNAi allele (UAS-nrx-1hpRNA, VDRC: 36326), neuronal and glial Huntington's disease (HD) model with dNRXN3 mutant (elavc155-GAL4/y1 w*; repo-GAL4,UAS-HTTNT231Q128/Experimental allele), glial HD model with dNRXN3 mutant (w1118/y1 w*; repo-GAL4,UAS-HTTNT231Q128/Experimental allele), and neuronal model with dNRXN3 mutant (elavc155-GAL4/y1 w*; UAS-HTTNT231Q128/Experimental allele). The gene discussed is LGALS4; the disease is juvenile Huntington disease.
