OMIA 000366-9913 : Fanconi syndrome in Bos taurus

In other species: dog , horse

Possibly relevant human trait(s) and/or gene(s) (MIM number): 227810

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.

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."

Breeds: Braunvieh, German Fleckvieh.

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.
