The median external masculinization score was 3.0 (2.5\u20135.0). Among individuals initially assigned female, 73% (33\/45) later underwent sex reassignment to male. Follicle-stimulating hormone levels increased significantly during puberty.

Intrafamilial phenotypes varied markedly, including primary ovarian insufficiency or irregular menstruation in women and oligospermia or DSD in men. The external masculinization score and penile length standard deviation score did not differ between missense and loss-of-function variants (median score \u22123.63 vs \u22124.71; all\n                      <jats:italic>P<\/jats:italic>\n                      &amp;gt; 0.05) and remained similar across functional domains; testis location scores and sex assignment were also comparable.
