Categories: Vision / eye phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 116200 (trait) , 600897 (gene)

Links to relevant human diseases in MONDO:

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2016

Species-specific description: Yuan et al. (2016) generated GJA8-deficient rabbits using CRISPR/Cas9 gene editing to develop a rabbit model for congenital cataracts. Rabbits with impaired GJA8 function presented with microphthalmia, small lens size and cataracts. (GMO)

Genetic engineering: Yes - variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing
