2bp insertion in the 5' region of the Gel coding sequence; results in a premature stop codon.
Gel9.3/Gel9.3 stage 15 embryos show lateral transverse (LT) muscle defects, including irregular growth and enlarged fibers, muscle dissociation, and muscle splitting, with asynchronous growth and sub-division into two fibers, leading to increased number of muscles; these muscles also show disrupted sarcomeric patterns.. In stage 16, these muscles show increased number of nuclei. Gel9.3/Gel9.3 stage 15 embryos also show a decrease in SBM and LO1 muscles.
Gel9.3/Gel9.8 stage 15 embryos show lateral transverse (LT) muscle splitting.
