Molecular basis: Stayner et al. (2017) reported two almost adjacent missense mutations (p.Ile681Asn and p.Ile687Ser) in complete linkage disequilibrium (and which can, therefore, be regarded as a single variant) within the TMEM67 gene as being likely causal of this disorder in two flocks (one Perendale and one Coopworth) located 500 kms apart and with no history of interbreeding within the last 40 years.
Clinical features: Stayner et al. (2017): "The kidney and liver abnormalities in the affected lambs were similar to those observed in the Meckel/Joubert/Nephronophthisis constellation of abnormalities in humans."
Pathology: Stayner et al. (2017): "Meckelin protein was expressed in affected and unaffected kidney epithelial cells by immunoblotting, and in primary cilia of lamb kidney cyst epithelial cells by immunofluorescence. In contrast to primary cilia of relatively consistent length and morphology in unaffected kidney cells, those of affected cyst-lining cells displayed a range of short and extremely long cilia, as well as abnormal morphologies, such as bulbous regions along the axoneme. Putative cilia fragments were also consistently located within the cyst luminal contents. The abnormal ciliary phenotype was further confirmed in cultured interstitial fibroblasts from affected kidneys. These primary cilia dysmorphologies and length control defects were significantly greater in affected cells compared to unaffected controls."

Variants
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.
