Weinberg-Shukron A, Renbaum P, Kalifa R, Zeligson S, Ben-Neriah Z, Dreifuss A, Abu-Rayyan A, Maatuk N, Fardian N, Rekler D, Kanaan M, Samson AO, Levy-Lahad E, Gerlitz O, Zangen D. A mutation in the nucleoporin-107 gene causes XX gonadal dysgenesis. J Clin Invest. 2015 Nov 2;125(11):4295-304. doi: 10.1172/JCI83553. PubMed PMID: 26485283; PubMed Central PMCID: PMC4639971.

From the abstract: "... XX female gonadal dysgenesis (XX-GD) is a rare, genetically heterogeneous disorder that is characterized by underdeveloped, dysfunctional ovaries ... Here, we report an extended consanguineous family .. in which 4 females exhibited XX-GD. ... we identified a recessive missense mutation in nucleoporin-107 (NUP107, c.1339G>A, p.D447N). ... NUP107 is a component of the nuclear pore complex ... In Drosophila, Nup107 knockdown in somatic gonadal cells resulted in female sterility, whereas males were fully fertile. Transgenic rescue of Drosophila females bearing the Nup107D364N mutation, which corresponds to the human NUP107 (p.D447N), resulted in almost complete sterility ..."
