Yes, you can marry, BUT, your chances of having kids with the Sickle Cell Trait is very high. This is a disease that has no cure, (except the Lord God heals), and the mental and physical strain, anguish, stress, energy, excruciating pains are nothing to write home about. SC & AS is a combination not to reckon with when it comes to having kids. So, think twice. Think about the suffering such child will go through. think about your own lives too and what you will go through with the never-ending crisis. It is not worth it. Lastly, with God, nothing is impossible.
