OMIA:002399-13180 : Cryptophthalmos in Nymphicus hollandicus (cockatiel)

Categories: Vision / eye phene

Possibly relevant human trait(s) and/or gene(s) (MIM number): 123570 (trait)

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Considered a defect: yes

Species-specific description: Buyukmihci et al. (1990): "Four unrelated cockatiels had various degrees of maldevelopment of the eyelids. Only 1 eye of the 8 was normal. The condition had features compatible with ankyloblepharon or cryptophthalmos. ... Anecdotal information along with our findings suggest that this condition, although uncommon, is widespread in the cockatiel population in the United States."

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