KUSA - There is new hope for couples who carry genes for genetic disorders.

A woman who had a family history of Gerstmann-Straussler-Scheinker disease (GSS) - a rare degenerative brain disorder successfully gave birth to healthy twins.

Genetic testing revealed she is a carrier of the GSS mutation and to ensure she didn't pass this trait down to her children, she underwent pre-implantation genetic diagnosis.

It was a procedure in which fertilized embryos are scanned for genetic disease before they are implanted.
