    Heterozygous Df(1)y74k24.1 mutant females exhibit a dilated cardiomyopathy phenotype, including an increased end-systolic dimension (EDD) and a decreased fractional shortening (FS) compared to controls. Bristles appear short and thin compared to wild type (Minute phenotype).

    Acts as a dosage sensitive maternal modifier of run : causes tergite defects in greater than 65% of run3 heterozygotes. Shows a dominant Minute phenotype: short fine bristles, delayed development and reduced viability. Both phenotypes are alleviated by maternal P{1BD#1}.
