Well it is more of a question of curiosity however I have anxiety problems that is genetic on my moms side n I do hv a twin brother who shared with symptoms I too hv been feeling maybe too has anxiety problems he just hasnt been diagnosed yet
If both twins are together in a sac, it could be possibel but if they are in separate sacs, then it is unlikely. If the mother has a catching disease, the children could have a side effect or get defected in a way, but this is only a possibilty.
Many variables to consider! Is the disease genetic?
