Came upon this:
Fortunato A, Giovanardi G, Innocenzi E, Mirabella M, Caviglia G, Lingiardi V, Speranza AM. Is It Autism? A Critical Commentary on the Co-Occurrence of Gender Dysphoria and Autism Spectrum Disorder. J Homosex. 2022 Jun 7;69(7):1204-1221. doi: 10.1080/00918369.2021.1905385. Epub 2021 Apr 14. PMID: 33852376.
From the abstract:
"We hypothesize that the traits often classified as autistic could be more accurately related to the distress and discomfort evoked by GD."
The journal doesn't look like a journal of psychatry or autism. I can only see the abstract from here pubmed.ncbi.nlm.nih.gov/33852376/ but I think that this bit "to provide, through the description of a clinical case, our reading and a possible interpretation of the correlation of these two conditions" means that they are talking about just one patient.
