Links to possible relevant human trait(s) and/or gene(s) in OMIM: 203100 (trait) , 606952 (trait) , 606933 (gene)
Single-gene trait/disorder: yes
Disease-related: yes
Key variant known: no
Year key variant first reported: 2025
Key variant is published: no
Cross-species summary: Congenital lack of pigment in most parts of the body. Due to a non-functional form of the enzyme tyrosinase. Also known as oculocutaneous albinism (OCA), acromelanism and as the Himalayan coat-colour pattern.
Species summary: Funk et al. (2025) used CRISPR-Cas9 in captive cane toads to create TYR knockout albinos. This phene includes references to studies involving gene edited or genetically modified organisms (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
