G15R
Analogous mutation in human ACTA1 implicated in myopathy, congenital, ACTA1-related; mutation carried on in vitro construct.
Flies carrying one copy of Act88FG15R in a Act88F6/+ background are completely flightless.
Flies carrying one copy of Act88FG15R in a Act88F6/+ background show intermediate defects in myofibril organisation in the indirect flight muscles. Z-discs are less regular than normal. The defects are stronger in flies carrying two copies of Act88FG15R in a homozygous Act88F6 background.
Closely packed Z-disc stacks or "zebra bodies" are seen in the indirect flight muscles of flies carrying one copy of Act88FG15R in a Act88F6/+ background.
Expression of Act88F+t4.0 in flies carrying one copy of Act88FG15R in a Act88F6/+ background rescues flight ability.
