i wanted to ask that are deaf and dumb problems genetic. because i want to marry a gal whose mom is deaf and dumb.. and she is deaf and dumb and is in the third generation. and her gal whom i wanna marry will be in fourth generation. the girls maternal uncle and grandfather also had the same problem of being deaf and dumb. so would this problem harm or continue in the next generation. i mean our children can also face the deaf and dumb problem.
It certainly sounds like the problem is autosomal dominant because of the strong family history in both males and females, but in order to know for sure we would have to know the actual diagnosis. If the problem is autosomal dominant, your child would have a 50% chance of inheriting the condition. You should speak with a genetic counselor before conception because there might be new treatments available for the condition. There also might be genetic screenings such as amniocentesis or chorionic villae sampling (CVS) that would allow you to prepare ahead for the condition should your child be affected or terminate the pregnancy if you choose. It may even be a condition that can be detected through preimplantation genetic diagnosis (PGD) so you could choose the unaffected embryos before beginning the pregnancy. No matter how you feel about the treatments available, it is something you should talk about with your fiancee before you get married. This is something she's lived with her whole life and she has probably formed a strong opinion about the options already.
Whether a girl whose siblings are dumb and deaf can also have the chances of giving birth to such children. But in her family history no one has ever been diagnosed with such problem. Is this deaf and dumb problem with her siblings is normal or genetic?
