[1] There is limited evidence from case reports linking the virus to a skin rash occurring in immunocompromised organ transplant recipients.

[2] HPyV7 was first discovered in 2010 by rolling circle amplification, a genetic technique that efficiently amplifies and detects circular DNA, such as a polyomavirus genome.

[1] In the 2015 taxonomic update to the polyomavirus group, the International Committee on Taxonomy of Viruses classified HPyV7 in the genus Deltapolyomavirus.

[9] HPyV7 has been associated in case reports with a skin condition in immunocompromised patients—HPyV7-related epithelial hyperplasia[10]—specifically lung transplant recipients on a regimen of immunosuppressive drugs.

The reported skin manifestations consisted of severely pruritic (itchy) velvet-textured plaques initially interpreted clinically as drug side effects.
