HCP5
The
fossil of an ancient virus that at one time infected people, but has now become an integral part of the human genome.[1]
One variation of HCP5 appears to provide some delay or resistance to the development of
AIDS when a person is infected with HIV. This variation of HCP5 frequently occurs in conjunction with a particular version of an immune system gene called HLA-B.[1]
HCP5 has been reported to become
upregulated after human papillomavirus infection and may promote the development of cervical cancer.[2][3]
