Write answer in between .Q:A healthy 30-year-old woman comes to the physician with her husband for preconception counseling. Her husband is healthy but she is concerned because her brother was recently diagnosed with a genetic liver condition for which he takes penicillamine. Her father-in-law has liver cirrhosis and a tremor. The results of genetic testing show that both the patient and her husband are carriers of a mutation in the ATP7B gene. Which of the following is the chance that this patients offspring will eventually develop the hereditary condition?? A: 0, B: 100, C: 75, D: 25, E: 50,  <response>: This is a question about calculating the risk of passing on a genetic mutation to offspring. The patient and her husband are both carriers of a mutation in the ATP7B gene, which causes Wilsons disease. Since they are both carriers, each of their offspring has a 25 chance of inheriting two mutated copies of the gene one from each parent and developing the disease. The patients brother and father-in-laws medical histories are irrelevant since we know the specific genetic mutation involved. D: 25
