TL;DR: The male-specific region of the Y chromosome, the MSY, differentiates the sexes and comprises 95% of the chromosome's length, and is a mosaic of heterochromatic sequences and three classes of euchromatics sequences: X-transposed, X-degenerate and ampliconic.
Journal ArticleDOI
Diverse spermatogenic defects in humans caused by Y chromosome deletions encompassing a novel RNA–binding protein gene
Renee Reijo,Tien-Yi Lee,Pia Salo,Raaji Alagappan,Laura G. Brown,Michael A. Rosenberg,Michael A. Rosenberg,Steve Rozen,Tom Jaffe,Donald Straus,Outi Hovatta,Albert de la Chapelle,Sherman J. Silber,David C. Page +13 more
TL;DR: The region contains a single–copy gene, DAZ (Deleted in AZoospermia), which is transcribed in the adult testis and appears to encode an RNA binding protein, and the possibility that DAZ is AZF should now be explored.
Journal ArticleDOI
The sex-determining region of the human Y chromosome encodes a finger protein
David C. Page,Rebecca Mosher,Elizabeth M. Simpson,Elizabeth M. C. Fisher,Graeme Mardon,Jonathan R. Pollack,Barbara McGillivray,Albert de la Chapelle,Laura G. Brown +8 more
TL;DR: The possibility that the Y-encoded finger protein is the testis-determining factor is discussed, and models of sex determination accommodating the finding of a related locus on the X chromosome are proposed.
Journal ArticleDOI
The AZFc region of the Y chromosome features massive palindromes and uniform recurrent deletions in infertile men.

TL;DR: The complete nucleotide sequence of AZFc was determined by identifying and distinguishing between near-identical amplicons (massive repeat units) using an iterative mapping–sequencing process.
Journal ArticleDOI
Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators

TL;DR: It is proposed that beyond its roles in testis determination and spermatogenesis, the Y chromosome is essential for male viability, and has unappreciated roles in Turner’s syndrome and in phenotypic differences between the sexes in health and disease.
