“…For 17β-HSD-3 deficiency, these studies were conducted in Israel ( n = 15; Rosler, Silverstein, &Abeliovich, 1996) and Brazil ( n = 10; Mendonca et al, 2000). Studies on both conditions from European countries showed sample sizes ranging from one to four (e.g., Aguilar-Diosdado, Gavilán-Villarejo, Escobar-Jiménez, Beltrán, &Grión, 1995; Boudon et al, 1995; Leinonen, Dunkel, Perheentupa, &Vihko, 1983; Wieacker &Von Mühlendahl, 1996). Knowledge about the genetic basis is continuously growing.…”
