Mapping: Medugorac et al. (2003) reported "the localization of the gene causing bovSMA within a genomic interval between the microsatellite marker URB031 and the telomeric end of bovine Chromosome (Chr) 24 (BTA24)" Krebs et al. (2006) refined the mapping "to an interval of approximately 0.8 cM at the very distal end of BTA24". Krebs et al. (2007) narrowed the location to a region containing three comparative positional candidate genes. In the course of their large-scale study of BovineSNP50 BeadChip haplotypes that are common but never homozygous, VanRaden et al. (2011) confirmed the mapping of this disorder to BTA24 at 58-63Mb (UMD 3.0 genome assembly).

Molecular basis: By examining three comparative positional candidate genes from their mapping results (see Mapping section), Krebs et al. (2007) reported strong evidence that this disorder in cattle is due to a mutation in "FVT1, encoding 3-ketodihydrosphingosine reductase, which catalyzes a crucial step in the glycosphingolipid metabolism". Specifically, the mutation is "a G-to-A missense mutation that changes Ala-175 to Thr". Interestingly, the FVT1 gene, officially known as KDSR, is not included in the list of genes in which mutations result in SMA in humans. In their table of reduced-fertility haplotypes, Cole et al. (2014) list this KDSR mutation as being the causal mutation for haplotype BHM, which is located at 62,118,139– 62,156,760bp on chromosome BTA24.

Breeds: Brown Swiss (Cattle) (VBO_0000166), Red Dane (Cattle) (VBO_0000353).

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.
