To accomplish this, GAS5 mRNA levels were evaluated by Next Generation Sequencing (NGS) technology and qRT-PCR assay in 10 patients with KS and 10 age-matched controls.
Since it has been shown that decreased Complex I protein levels could induce apoptosis, wehypothesizethat the above-mentioned MT-ND6 down-expression contributes to the wide range of phenotypes observed in men with KS.
Hypergonadotropic hypogonadism was confirmed in both KS and HGA patients, but was more precocious in the latter, as demonstrated by the earlier increase in gonadotropins and the decrease in testosterone, DHEA-S and inhibin B. Prolactin was significantly higher in HGA patients, starting from subgroup 2.
This RAD9A-dense body is closely associated with the inactive X in HeLa cells but not in other cell types analyzed including a Klinefelter's syndrome-derived line containing multiple Xi.

13 Klinefelter syndrome patients also underwent Thyrotropin-Releasing Hormone testing to evaluate hypothalamic-pituitary function. fT3 levels were significantly lower in Klinefelter syndrome patients than in age-matched controls (p < 0.001).
The systems biology approaches together pointed to novel aspects of KS disease phenotypes including perturbed Jak-STAT pathway, dysregulated genes important for disturbed immune system (IL4), energy balance (POMC and LEP) and erythropoietin signalling in KS.

Sertoli cell dysfunction was investigated in a subgroup using a three-stage immunoperoxidase technique for detection of cytokeratin-18 (CK-18).The prevalence of THF was 13.4%. uTHF was found in 11 men (2.9%), the pattern was bilateral in four while other four had bTHF in the other testis. pTHF was detected in eight cases (2.1%), and except for one case with Klinefelter's syndrome, pTHF was in all cases occurring unilaterally. bTHF was detected in 32 cases (8.4%), bilaterally in 17 (53%).

Since GPR30 is essential to mediate estrogen effects over steroidogenesis, our data illustrate that GPR30 may underpin the testicular alterations observed in KS men.
Herein, we evaluated GPR30, ERα, and ERβ mRNA expression in testis of KS men and men with 46XY karyotype by reverse transcriptase and quantitative PCR.
In this consideration, he was referred for postoperative somatostatin analogue treatment to control GH hypersecretion.The misdiagnosis or delayed diagnosis of KS is mainly because of substantial variations in clinical presentation and insufficient professional awareness of the syndrome itself.
Cases with Turner syndrome showed values below 3 SDs for SHOX and VAMP7 genes, and cases with Klinefelter syndrome showed values above 3 SDs for SHOX and VAMP7 genes.
