592bp deletion, which is predicted to truncate the par-6 protein within its single, C-terminally located PDZ domain.
Homozygous tracheal terminal cells show a reduction in branching compared to wild type, have no gas-filled lumen and have very abnormal branch tip morphology (including large varicosities and membrane-filled cytoplasmic swellings). This phenotype is completely recessive.
Homozygous embryos do not have holes in the cuticle, although they show head involution defects.
par-629VV/par-615N embryos have occasional small holes in the cuticle.
