Apscaviroids have a circular RNA molecule with 297-370 nucleotides. The genus belongs to the family Pospiviroidae (see the genus Pospiviroid for details) and the viroids have a central conserved region (CCR) in the RNA molecule and lack the ability to self-cleave through hammerhead structures. The genus is defined by the nucleotide sequence in the CCR.
