Melbourne, May 26 Australian scientists have claimed to be close to a medical breakthrough which will help treat infants with a genetic disorder that causes Floppy Baby Syndrome.

The researchers claimed to have found a replacement of skeletal muscle actin, a form of protein, which can be used to treat babies suffering from FBS caused due to protein deficiency at the time of birth.

The genetic experiments on mice have shown that replacing that protein with another one known as heart actin can reverse the effects of the disease, said Nigel Laing of West Australia Institute for Medical Research.

" Basically we hope that we may be able to find a drug that will make the heart gene work in skeletal muscles," Laing was quoted as saying by ABC report.
