OMIA:002762-61156 : Smith-Magenis syndrome, RAI1-related in Arvicanthis niloticus (African grass rat)

Categories: Nervous system phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 607642 (gene) , 182290 (trait)

Mendelian trait/disorder: yes

Considered a defect: unknown

Key variant known: yes

Key variant is published: no

Species-specific description: Xie et al. (2023) used CRISPR genome editing to create RAI1 knockout African grass rats. RAI1 "haploinsufficiency is responsible for Smith-Magenis Syndrome, a neurodevelopmental disorder characterized by sleep disturbance in humans." (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
