Hi, good morning.

You're actually right, sickle cell which comes as the unawareness of parents who didn't understand the importance of blood group probably genotype and got married without checking, if unfortunately they give birth to AS children, life becomes hell to the innocent children. About your neighbor, I feel sad for her and thankfully her mom is there to assist her. I so much believed the world would be good if diseases are eradicated. Best of luck.
