This term is obsolete.
Spherical viruses with T numbers greater than or equal to 7 are skewed. They are therefore described as either right-handed (dextro) or left-handed (laevo).

GO:0039620 JSON

T=7 icosahedral viral capsid

Cellular Component

Definition (GO:0039620 GONUTS page)

The protein coat that surrounds the infective nucleic acid in some virus particles where the subunits (capsomeres) are arranged to form an icosahedron with T=7 symmetry. The T=7 capsid is composed of 12 pentameric and 60 hexameric capsomeres.

Comments

Spherical viruses with T numbers greater than or equal to 7 are skewed. They are therefore described as either right-handed (dextro) or left-handed (laevo).
