XXY syndrome

08/01/2012 - "This finding may prove helpful in similar cases with symptoms of Klinefelter syndrome, but which exhibit an absence of the cell line 47,XXY in peripheral blood."
03/01/2011 - "In our study we found 12 patients (5%) with 47,XXY karyotype (Klinefelter syndrome), but these patients didn't have microdeletion of Y chromosomes. "
12/01/2010 - "Controlled studies should be done to determine the best age for TESE-ICSI in 47.XXY homogeneous Klinefelter syndrome patients."
01/01/2009 - "Klinefelter syndrome (47,XXY) was initially described in the context of its endocrinologic and physical features; however, subsequent studies have revealed specific impairments in verbal skills and social functioning. "
03/15/2008 - "The goal of this study was to expand the description of the cognitive development phenotype in boys with Klinefelter syndrome (47,XXY). "

07/01/2000 - "The authors report on a 23-year-old man with Klinefelter syndrome (47,XXY) and bipolar disorder who was treated successfully with unilateral DBS of the thalamic Vim for essential tremor."

07/01/2000 - "The authors report on a 23-year-old man with Klinefelter syndrome (47,XXY) and bipolar disorder who was treated successfully with unilateral DBS of the thalamic Vim for essential tremor."

06/01/2013 - "The purpose of this study was to extend the detection to include common sex chromosome aneuploidies (SCAs): [47,XXX], [45,X], [47,XXY], and [47,XYY] syndromes. "
05/01/2013 - "Some studies reported that 47,XXY spermatogonia are capable of completing spermatogenesis leading to the production of mature spermatozoa with increased aneuploidies. "
12/01/2011 - "In this study, we have assessed the degree of mosaicism in somatic and germinal tissues in KS, the meiotic competence of 47,XXY germ cells and the aneuploidy rate of post-reductional cells. "
05/20/2014 - "Furthermore, 15 fetuses with sex chromosome aneuploidies (10 45,X, 2 47,XYY, 2 47,XXX, and 1 47,XXY) were detected. "
01/01/2014 - "This was a case-control study of 177 stored maternal plasma samples, obtained before fetal karyotyping at 11-13 weeks of gestation, from 59 singleton pregnancies with fetal sex chromosome aneuploidies (45,X, n = 49; 47,XXX, n = 6; 47,XXY, n = 1; 47,XYY, n = 3) and 118 with euploid fetuses (46,XY, n = 59; 46,XX, n = 59). "

04/01/1992 - "Chromosomal study revealed 47, XXY and hormonal quantification showed hypergonadtropic hypogonadism. "
01/01/1990 - "Hormonal examination revealed hypergonadotropic hypogonadism and cytogenetic studies a 47,XXY karyotype. "
06/01/2011 - "The more complex physical, medical and psychological phenotypes of 48,XXYY, 48,XXXY and 49,XXXXY syndromes make distinction from 47,XXY important; however, all of these conditions share features of hypergonadotropic hypogonadism and the need for increased awareness, biomedical research and the development of evidence-based treatments."
01/01/2009 - "Although the hypogonadism typically found in 47,XXY males may contribute to the decreased brain volume, the observation that 47,XXX females also show decreased brain volume in the presence of normal pubertal maturation suggests a possible direct dosage effect of X chromosome genes. "
01/01/2008 - "The boys with 46,XX and 47,XXY karyotypes developed hypogonadism in puberty, but androgen secretion in 47,XYY boys remained normal. "
