  • Title: Sexual and somatic determinants of the human Y chromosome: studies in a 46,XYp- phenotypic female.
    Author: Rosenfeld RG, Luzzatti L, Hintz RL, Miller OJ, Koo GC, Wachtel SS.
    Journal: Am J Hum Genet; 1979 Jul; 31(4):458-68. PubMed ID: 573550.
    Abstract:
    A case of a 46,XYp- phenotypic female provided an opportunity to evaluate both sexual and somatic determinants for the Y chromosome. The patient had multiple stigmata of Turner syndrome, but normal stature. Laparotomy revealed a normal uterus and tubes, with 1.5 cm undifferentiated gonads. Serological tests for H-Y antigen (ostensibly the product of Y-chromosomal testis-determining genes) indicated absence of the H-Y+ phenotype normally associated with the intact Y chromosome. We conclude that genes exist on the short arm of the human Y chromosome which both suppress some of the somatic stigmata of Turner syndrome and determine normal expression of H-Y antigen and testicular differentiation of the primitive gonad. Our data are consistent with the view that H-Y genes comprise a family of testis-determinants, and that loss of a critical moiety is inconsistent with normal development of the male gonad.
