Ovarian dysgenesis-9 (ODG9) is characterized by severe nonsyndromic primary ovarian insufficiency with primary amenorrhea, hypoplastic or absent ovaries, and delayed bone age. Patient cells show evidence of chromosomal instability (Smirin-Yosef et al., 2017; Heddar et al., 2022).
For a general phenotypic description and discussion of genetic heterogeneity of ovarian dysgenesis, see ODG1 (233300). [from
