Mendelian trait/disorder: unknown

Considered a defect: yes

Species-specific description: Without citing references, Pan et al. (2015) explained that "In recent years, some rex rabbits have shown wrinkles in abdomen and extremities during production; this phenotype is known as plaice. The skin size of wrinkle rabbits was found to be 15% larger than that of un-wrinkle animals, with the same quality fur."

Molecular basis: From a gene transcription study, Pan et al. (2015) reported that "A total of 308 differentially expressed genes were obtained by transcriptome analysis of plaice and un-plaice phenotype animals; 209 additional differentially expressed genes were not found in any database. These genes included 49 that were only expressed in plaice skin rabbits."
