In addition to humans and flies, some plants also make use of the XX/XY dosage compensation systems. Silene latifolia plants are also either male (XY) or female (XX), with the Y chromosome being smaller, with fewer genes expressed, than the X chromosome.
Gain of an X chromosome, [20] Klinefelter syndrome, [21] and XX male syndrome [22] are risk factors linked to male breast cancer. In females, there is no evidence that trisomy X or tetrasomy X females are at higher risk of cancer. [19] Breast cancer and ovarian cancer, particularly more aggressive strains, commonly lack an Xi and have two Xa's ...
The implications of CASI extend to human health, especially in relation to sex-specific diseases. While hormonal influences have long been studied in diseases such as cancer (e.g., prostate cancer, ovarian cancer), CASI suggests that the cellular sex identity may also contribute to disease susceptibility and progression.

However, this pattern has been proven wrong for many cancer types, suggesting that some cancers may be polyclonal in origin. [46] Besides, measuring the methylation (inactivation) status of the polymorphic human androgen receptor (HUMARA) located on X-chromosome is considered the most accurate method to assess clonality in female cancer ...

There has been evidence that the nonsense-mediated mRNA decay pathway participates in X chromosome dosage compensation in mammals. In higher eukaryotes with dimorphic sex chromosomes, such as humans and fruit flies, males have one X chromosome, whereas females have two.
Obama’s actions followed a September declaration by Sylvia Mathews Burwell, secretary of the Department of Health and Human Services, that her agency would begin the process of reworking the patient caps to expand access. Noting that medication-assisted treatment “is a high priority” for HHS, a department spokesperson told HuffPost in ...
