The remaining participants were classified as either heterosexual or asexual… It is conceivable that the childhood criteria for GID may “scoop in” girls who are at relatively low risk for adolescent/adult gender dysphoria that revolves so much around somatic indicators.”

Gerrit, Gender Identity and Autism Spectrum Disorders, Yale J Biol Med. 2015 Mar; 88(1): 81–83, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4345542/ – summary of literature treating gender identity in patients on ASD spectrum; “critical shortcomings in our current understanding.”  “In a study of pre-pubertal male and female children with gender dysphoria followed-up approximately 10 years later, only 27 percent of children with gender dysphoria remained gender dysphoric at follow-up. Of those individuals who no longer expressed gender dysphoria at follow-up, a significant portion (all female and half the male participants) expressed a non-heterosexual sexual orientation. Thus, gender concerns in neurotypical children prior to puberty may represent a developmental process related to both gender and sexuality for many individuals. ”

Epub 2017 Feb 20, https://www.ncbi.nlm.nih.gov/pubmed/28221049. Study of nearly 5000 young people. Gender nonconforming behavior in early childhood was strongly predictive of adolescent homosexuality. “Levels of gender-typed behavior at ages 3.5 and 4.75 years, although less so at age 2.5 years, significantly and consistently predicted adolescents’ sexual orientation at age 15 years… These results suggest that the factors contributing to the link between childhood gender-typed behavior and sexual orientation emerge during early development. Some of those factors are likely to be nonsocial, because nonheterosexual individuals appear to diverge from gender norms regardless of social encouragement to conform to gender roles.”
