Species-specific description: Information listed here was previously listed under OMIA:000366-9615 : Fanconi syndrome in Canis lupus familiaris
Mapping: In an unpublished thesis, Farias (2011) reports a genome-wide linkage study involving 59 related Basenjis comprising 22 affecteds and 37 normals, each genotyped with 325 microsatellites, that mapped this disorder to chromosome CFA3. Fine mapping of this chromosome with 29 additional microsatellites narrowed the candidate region to 2.7Mb (40,537,065 bp and 43,218,050 bp), which contains 11 identified genes. The detailed information was published in 2024 (Farias et al. 2024).
Molecular basis: In an unpublished thesis, Farias (2011) reported whole-genome sequencing one affected Basenji and three unaffected dogs from other breeds, which eventually led to identification of a candidate causal mutation: "317 bp of exon 14 were deleted starting at the second exon14 nucleotide and extending into the 3’ untranslated region of FAN1" (the gene encoding Fanconi anemia-associated nuclease 1). This mutation showed almost perfect association with Fanconi genotype in 78 Basenjis (there being one exception, namely an unaffected dog that was homozygous for the deletion). This work was later published in a peer-reviewed journal (Farias et al. 2024).
Clinical features: Fanconi syndrome is a rare condition in dogs which results in abnormal renal function. More specifically, it causes reduced function of the proximal convoluted tubules (Yearley et al., 2004), resulting in reduced reabsorption of water, nutrients and electrolytes from the tubular fluid and their eventual loss in urine. The clinical consequences of this disease for the animal include polyuria and polydipsia, dehydration, weight loss and muscle weakness (Yearley et al., 2004). Most cases progress to renal failure within a few years of the onset of initial clinical signs Bovée et al. (1978, PMID:684432). IT thanks DVM student Harry Cahill, who provided the basis of this contribution in May 2023.
Genetic testing: The website of the Orthopedic Foundation for Animals (OFA) reports the availability of a DNA test for this disorder in the Basenji breed: https://ofa.org/diseases/?breed=BJ. The basis of this test was initially described in a PhD thesis by Farias (2011) and a conference proceeding (Farias et al., 2012). Thanks to Mario Van Poucke and Kathy Davies for alerting FN to this thesis. The detailed information was published in 2024 (Farias et al. 2024).

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.
