Two SRY-negative XX male
brothers without genital ambiguity.
In an attempt to produce an all-female population, masculinization of a normal mixed-sex population will be the initial step according to the laws of Mendelian inheritance (the offspring of an XX female and an XX male
will be all female).
Earlier it was known as 46 XX male syndrome or 46 XX sex reversal2.
Clinical, hormonal and cytogenetic evaluation of 46, XX male and review of the literature.
Clinical, endorinological, and epigenetic features of the 46 XX male syndrome
In our June issue we will cover the following topics; Late-Onset Hypogonadism in Male Patients Over 60 Years of Age with Metabolic Syndrome, Depression, Anxiety and Quality of Life Among Adult Turkish Patients with Type 1 Diabetes Mellitus, Polycystic Ovary Syndrome and the Relationship of Cardiovascular Disease Risk, Evaluation of Preventive Studies in Type 1 Diabetes Mellitus, Primary Thyroid Lymphoma Diagnosed During Pregnancy: A Case Report, 46, XX Male
Syndrome, Bluish Discoloration with Thyrotoxicosis.
46, XX male syndrome--testicular disorder of sexual differentiation (DSD) is a rare condition characterized by a spectrum of clinical presentations, ranging from ambiguous to normal male genitalia.
Key words: 46, XX male syndrome, testicular disorder, SPY gene, primary hypogonadism, chromosomal abnormalities, infertility
Clinical, hormonal and cytogenic evaluation of 46 XX male and review of the literature.
Using dozens of DNA probes that attach to specific genetic sequences, the scientists compared the structures of Y chromosomes from an XX male
and an XY female.
Moreover, in males, a single gene on the Y chromosome, known as SRY, is critical for testis development, and translocation of the SRY gene to the X chromosome explains testis development in 90% of XX males
Using a molecular test dubbed a "Noah's Ark blot," the London researchers found the gene in blood cells of human XX males
, and in male chimpanzees, rabbits, pigs, horses, cattle and tigers.
