<s>[INST] Hello doctor, I was born with a structural birth defect where my left hand is completely deformed. My left arm is normal from the wrist and above. I would like to know if this defect is hereditary if I try to have a child. What are the risk for me as a father passing any defects to my future children? [/INST] Hello. I can understand your concern. It will be of great help if you can send me the picture of your deformity. I will be happy to help you further. </s>
