Cytology
Description

Imprecise excision of the insertion in fendGS1092, resulting in a 643bp deletion that removes the translation start site and signal sequence of fend (nucleotides 240-883 relative to the 5' end of EST LD02203 are deleted).

      Reference

      Mutants show no obvious defects in the overall development of the central nervous system, muscles or peripheral nervous system. fendB23/Df(1)18.1.15 larvae show defects in the innervation pattern of muscle 12; the terminal branch is often accompanied by additional varicosities on the neighbouring muscle 13 (22.7% of hemisegments).
