a psychological condition marked by significant emotional distress and impairment in life functioning, caused by a lack of congruence between gender identity and biological sex assigned at birth.
Also called gender identity disorder.
Some transgender individuals and their advocates object to the use of the word "disorder" to describe this condition and therefore reject use of the variant term gender identity disorder. However, others feel that classifying it as a disorder may facilitate access to medical care related to the condition.
