Molecular basis: In a neat piece of comparative detective work, Lunden et al. (2002; Genome Research 12:1885-1888) investigated whether the fishy off-flavour occasionally reported in cow's milk could be an animal model of fish-odor syndrome in humans, an inborn error of metabolism characterised by a fishy body odor, and known to be due to mutations in the gene for flavin-containing mono-oxygenase 3 (FMO3). They were able to show that this is, indeed, the case: fishy off-flavor in cow's milk is due to a nonsense mutation (R238X) in FMO3 in cattle [FN 13 Jan 2003]
Breed:
Swedish Red and White (Cattle) (VBO_0000392).

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.
