Species-specific description: Zhang et al. (2022): "Fam83h mutations cause human amelogenesis imperfecta (AI), an inherited disorder characterized by severe hardness defects in dental enamel. ... a large deletion of the Fam83h gene (900 bp) was generated via a dual sgRNA-directed CRISPR/Cas9 system in rabbits." This study involves genetically modified organisms (GMO).

Clinical features: Zhang et al. (2022): "Abnormal tooth mineralization and loose dentine were found in homozygous Fam83h knockout (Fam83h-/-) rabbits compared with WT rabbits. In addition, reduced hair follicle counts in dorsal skin, hair cycling dysfunction and hair shaft differentiation deficiency were observed in Fam83h-/- rabbits. Moreover, X-rays and staining of bone sections showed abnormal bending of the ulna and radius and an ulnar articular surface with insufficient trabecular bone in Fam83h-/- rabbits."

Breed: New Zealand White (Rabbit) (VBO_0001269).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
