3. Hereditary
Around half of all cases of NF2 are hereditary meaning that they were passed down from parents. Some hereditary diseases are dominant in specific demographics such as those with African ethnicity. Other diseases are more common in women. That being said, NF2 affects all demographics equally thus you have an equal chance of developing the disease hereditarily regardless of your gender, ethnicity, and race.
It’s worth noting that you’re not guaranteed to develop NF2 and schwannomas even if one of your parents suffered from it so there’s no need to ring the alarm bells just because your family has a history of NF2. However, if you notice a schwannoma developing and know that one of your parents suffered from NF2 then you might have developed the condition hereditarily. Be sure to get yourself checked by a medical professional as soon as you realize you have a schwannoma.
