Key variant known: yes
Year key variant first reported: 2021
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 description: Kurtz et al. (2021) "successfully generated a knockout of the porcine SRY gene by microinjection of two CRISPR-Cas ribonucleoproteins, targeting the centrally located "high mobility group" (HMG), followed by a frameshift mutation of the downstream SRY sequence. This resulted in the development of genetically male (XY) pigs with complete external and internal female genitalia, which, however, were significantly smaller than in 9-mo-old age-matched control females. Quantitative digital PCR analysis revealed a duplication of the SRY locus in Landrace pigs similar to the known palindromic duplication in Duroc breeds. Our study demonstrates the central role of the HMG domain in the SRY gene in male porcine sex determination." These animals are considered genetically-modified organisms (GMO).
