Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 203100 (trait) , 606952 (trait) , 606933 (gene)

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Considered a defect: 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-specific description: Li et al. (2023): "using the African striped mouse (Rhabdomys pumilio), we describe TIGER (targeted in vivo genome editing in rodents), a method that relies on a simple intraoviductal injecting technique and uses recombinant adeno-associated viruses (rAAVs) as the sole vehicle to deliver reagents into pregnant females. We demonstrate that TIGER generates knockout and knockin (up to 3 kb) lines with high efficiency." One of the lines is a TYR knockout that resulted in albino animals. This study involves genetically modified organisms (GMO).

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
