2bp deletion in the 5' region of the Gel coding sequence; results in a premature stop codon.
increased cell number | embryonic stage 15 (with Gel9.3)
viable
lateral transverse muscle cell | embryonic stage 15 | increased number (with Gel9.3)
muscle cell of lateral oblique muscle 1 | decreased number | embryonic stage 15 (with Gel9.3)
segment border muscle cell | decreased number | embryonic stage 15 (with Gel9.3)
Gel9.3/Gel9.8 stage 15 embryos show lateral transverse (LT) muscle splitting.
