Dysphansync
Dysphansync describes someone whose sex and gender are incongruous/do not match. It is not synonymous with trans, because sex can be modified, and trans refers to sex/gender assigned at birth — not current sex/gender.
However, it is exclusive to trans people, because someone's gender and sex cannot be uncorrelated without being different from what they were born with or assigned. This would meet the criteria for someone identifying as transgender.
It is also another way to refer to a transgender person who has not yet medically transitioned. A medically transitioned trans person with gender-affirming SRS/GRS is cibinsync, but a transsex transgender individual can still be dysphansync, because they may have medically transitioned to a sex that does not match their gender. In other words, they received SRS/GRS, but it did not affirm their gender by matching it.
The opposite of dysphansync is cibinsync.
