Species-specific description: Fan et al. (2018) "describe the generation of a sheep model for CF using CRISPR/Cas9 genome editing and somatic cell nuclear transfer (SCNT) techniques" and propose "the generation of specific human CF disease–associated mutations in sheep [to] ...advance personalized medicine for this common genetic disorder." The same research team later developed models for the most common CSFR mutations found in human patients in the USA: "we describe the generation of CFTRF508del/F508del and CFTRG542X/G542X lambs using CRISPR/Cas9 and somatic cell nuclear transfer (SCNT)." (Perisse et al., 2021) (Genetically-modifed organisms; GMO) (Entry was edited by Hannah Edgell 24/08/2022)

Molecular basis: Fan et al. (2028) " generated cells with CFTR gene disruption [in exon 2 and exon 11] and used them for production of CFTR–/– and CFTR+/– lambs. The newborn CFTR–/– sheep developed severe disease consistent with CF pathology in humans." Perisse et al. (2021) "introduced either F508del or G542X mutations into sheep fetal fibroblasts that were subsequently used as nuclear donors for SCNT. The newborn CF lambs develop pathology similar to CFTR -/- sheep and CF patients. Moreover, tracheal epithelial cells from the CFTRF508del / F508del lambs responded to a human CFTR (hCFTR) potentiator and correctors, and those from CFTRG542X / G542X lambs showed modest restoration of CFTR function following inhibition of nonsense-mediated decay (NMD) and aminoglycoside antibiotic treatments."

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

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.
