      Homozygous embryos exhibit severe loss of PNS neurons and a significant increase in size of remaining neurons. Embryos arrest in cycle 16.

      (Bhat et al., 1996)

      Homozygous embryos exhibit pathfinding and organization defects and loss of neurons.

      P{lacW} insertion can be excised and revert the lethal phenotype to wild type. Phenotypic analysis provides an allelic series: nebk00802 < barrk14014 < barrk14028 < barrk00310 < barrk13903 < barrk04805 < barrk04912.

      (Kania et al., 1995)

      P{lacW} insertion is revertible.
