Cross-species summary: This is type of XY difference of sexual development (XY DSD) due to variation in the SRY gene. In humans called 46,XY sex reversal 1. Renamed in OMIA from "Ovotesticular DSD (Disorder of Sexual evelopment)" [29/09/2023]. Previously this phene ID was named in OMIA 'Sex reversal: XY female, SRY-negative'

Species-specific name: 54,XY sex reversal, SRY-related

Species-specific description: Information previously listed under OMIA:002753-9940 [01/10/1023]

Molecular basis: Heidari et al. (2023) investigated a hermaphroditic Shal sheep with an XY karyotype and detected a possible causal single nucleotide substitution in the promoter region of the SRY gene (AF026566.1:299T>G).

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Breed: Shal, Iran (Islamic Republic of) (Sheep) (VBO_0016099).
