She told me to change her Genotype to SS because she cannot marry him- Doctor narrates ordeal with lady dating older man

A doctor shared a story on social media about a young woman who, while dating an older man, asked him to lie about her genotype results. 

The woman and her partner visited his hospital to confirm their genotypes, revealing that she was AA while her partner was AS. 

Later, she approached the doctor privately, pleading for him to alter the results. She explained that she cannot marry her grandfather.

He wrote: “Young girl and old man about to get married came for genotype test, lady is AA and man is AS she comes to see me privately to tell the man she’s SS cos she cannot marry her grandfather.

Why put yourself in this mess in the first place.”
