Cross-species summary: This is a type of XX difference of sexual development (XX DSD) due to variants in the CYP17A1 gene.
Species-specific description: Zhai et al. (2022) report production of all-female (AF) common carp: "Male and female heterozygous cyp17a1-deficient common carp were first obtained using ... (CRISPR/Cas9) technique. An all-male phenotype for homozygous cyp17a1-deficient carp, regardless of the individuals’ sex-determination genotypes (XY or XX), has been observed. A male-specific DNA marker ... was used to screen the neomale carp population with the XX genotype from the cyp17a1-deficient carp. These neomale carp develop a normal testis structure with normal spermatogenesis and sperm capacity. The neomale common carp were then mated with wild-type (WT) females (cyp17a1+/+ XX genotype) using artificial fertilization. All the AF offspring sample fish from the neomale-WT female mating were confirmed as having the cyp17a1+/− XX genotype, and normal development of gonads to ovaries was observed in 100.00% of this group ... . ... The average body weight of cyp17a1+/− XX females was higher ... than that of the control common carp." This study involves genetically modified organisms (GMO).
Have human generated variants been created, e.g. through genetic engineering and gene editing
