An NGO was contacted by an impoverished married man with sickle cell disease who complained that one of their three children, a 5-year-old daughter, was frequently ill. They sought assistance and went to a hospital to perform several tests. The little girl is an SS, according to the tests.
Given that the father is SC and the mother is AA, the outcome shocked the parents. This means that none of the couple’s biological children could possibly be SS. Since both the mother and the father must pass on the defective form of the sickle cell gene for a child to be affected, it is still scientifically impossible for any of the mother’s biological children to be SS, even in the worst-case scenario in which the mother commits paternity fraternity.
The mother complied with the advice to repeat her genotype tests, and the results from various laboratories showed that she is in fact AA. Their daughter was still an SS.
The man returned to the state government hospital where the child was born. The hospital repeated the tests, and the results were exactly the same (Mum-AA, Dad-SC, Daughter-SS). The possibility that the baby may have been switched at birth is supported by all available evidence.
