Does anyone know when they stated testing for “spinal muscular atrophy” on the first trimester genetic testing

I had a baby in 2018 and was fine, unsure what they actually tested for. My sister is currently pregnant and she is a carrier. She had a baby in 2015 and they did not test for that at that point.
