OMIA:000366-9913 : Fanconi syndrome in Bos taurus (taurine cattle)
Categories: Renal / urinary system phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2016
Cross-species summary: Also known as Fanconi-Bickel Syndrome (FBS)
Molecular basis: Burgstaller et al. (2016) have provided strong evidence that the FH2 frameshift mutation (see OMIA 001958-9913), namely c.771_778delTTGAAAAGinsCATC (rs379675307) in SLC2A2, is actually causative of Fanconi-Bickel syndrome in Fleckvieh cattle.
Joller et al. (2018) reported the same likely causal variant in a Swiss Braunvieh calf.
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: Joller et al. (2018): "The clinical examination [of the Braunvieh calf] showed stunted growth, polyuria and polydipsia, as well as poor claw horn and coat quality. Necropsy revealed a pale cortex of the kidneys and a unilateral renal hypoplasia. Histology showed tubulonephrosis of the proximal tubules with protein- and glucose-rich contents. Glycogen accumulation was not evident in any organ. This finding is different from the reported lesions in two previously described GLUT2-deficient Fleckvieh heifers. In the presented case, growth retardation mainly seems to be associated with renal dysfunction."
Brown Swiss (Cattle) (VBO_0000166),
Fleckvieh-Simmental, Germany (Cattle) (VBO_0002354).

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
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.
