BACKGROUND SOX9 mutations cause the skeletal malformation syndrome campomelic dysplasia in combination with XY sex reversal. Studies in mice indicate that SOX9 acts as a testis-inducing transcription factor downstream of SRY, triggering Sertoli cell and testis differentiation. An SRY-dependent testis-specific enhancer for Sox9 has been identified only in mice. A previous study has implicated co...
On Thursday 9 May 1991, the world awoke to front-page news of a breakthrough in biological research. From Washington to Wollongong, newspapers, radio and TV were abuzz with the story of a transgenic mouse in London called Randy. Why was this mouse so special? The mouse in question was a chromosomal female (XX) made male by the presence of a transgene containing the Y chromosome gene Sry This se...
Here, we describe a 3-month-old XX male French Bulldog. The diagnosis was based on the clinical signs, gonadal histology and cytogenetic analysis. Additionally, the dog was confirmed to be Sry negative by semi-quantitative reverse transcription polymerase chain reaction (sqRT-PCR). Canine Sry-negative XX sex reversal is a disorder of gonadal development where individuals who have a female karyo...
Since Indonesia reported its first case of COVID-19 in the capital, Jakarta, early March 2020, pandemic has affected 102,051,000 lives. In second week month, government mandated all sectors to take necessary actions curb spread. The research set out evaluate how disaster emergency response was carried amid Special Region Yogyakarta (SRY). employs qualitative observation adaptive governance vari...
Sex determination in infants and children with ambiguous genitalia usually necessitates time-consuming and costly karyotyping .We have evaluated a simple,rapid and reliable method of postnatal sex determination by amplification of X and Y specific microsatellite markers DXS6797 and SRY respectively by polymerase chain reaction(PCR). Three probands M78, M59 and M61 with ambiguous genitalia were ...
Females with XY gonadal dysgenesis are sterile, due to degeneration of the initially present ovaries into nonfunctional streak gonads. Some of these sex-reversal cases can be attributed to mutation or deletion of the SRY gene. We now describe an SRY-deleted 47,XXY female who has one son and two daughters, and one of her daughters has the same 47,XXY karyotype. PCR and FISH analysis revealed tha...
Virilisation of the XX foetus is the result of androgen excess, resulting most frequently from congenital adrenal hyperplasia in individuals with typical ovarian differentiation. In rare cases, 46,XX gonads may differentiate into testes, a condition known as 46,XX testicular disorders of sex development (DSD), or give rise to the coexistence of ovarian and testicular tissue, a condition known a...
A male patient is reported with a 45,X karyotype and Leri-Weill dyschondrosteosis (LWD). FISH analysis with SHOX and SRY gene probes was carried out. One copy of both SHOX and SRY was detected in interphase nuclei, clarifying the origin of LWD and the male phenotype. Molecular results suggested that the 45,X karyotype arose through two independent events. The first occurred at paternal meiosis ...
