摘要

Turner syndrome (TS) affects one in 2500–3000 live-born girls, and is the most prevalent female sex chromosomal disorder in humans, resulting from the loss of all or part of one of the two X chromosomes (Sybert and McCauley 2004). About 50% of TS patients carry a 45, X monosomy, the rest being mosaics or structural chromosome abnormalities. TS patients’ phenotype is variable, and the wide spectrum of clinical features includes: short stature, ovarian dysgenesis, lymphedema, cardiovascular defects and renal malformation. Diabetes mellitus is also present at a rate two to four times higher than in the general population (Elsheikh et al. 2002), consistent with the finding of a relative insulin deficiency in TS on a non-immune basis, suggesting that haploinsufficiency for X-chromosome gene(s) impairs beta-cell function predisposing to diabetes mellitus in TS (Bakalov et al. 2004). The loss of the short arm of chromosome X (Xp), common to all TS, generally results in the full syndrome phenotype (Elsheikh et al. 2002).
