Both [[AMAB]]/CTM and [[AFAB]]/CTF individuals with this variation seem to be abnormally tall, which causes thinner bones and a higher chance of injury due to the thin nature of the bones. They also tend to have high blood sugar, which causes them to gain weight and have a larger liver. |

The cause of this variation appears to be when there is a mutation in ones ''CYP19A1'' gene (the gene directly connected to an enzyme called aromatase, which controls estrogen and testosterone production.) Usually during fetal development, aromatase converts androgens/estrogens in the placenta, which is the link between the mother's blood supply and the fetus. This conversion in the placenta prevents androgens from directing sexual development in fetuses, which is what causes a long-term effect on the fetus's growth within it's parent.<ref>https://medlineplus.gov/genetics/condition/aromatase-deficiency/#causes</ref> |
