OMIA 001565-9913 : Abortion and stillbirth, MIMT1-related in Bos taurus

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2010

Molecular basis: Flisikowski et al. (2010) described a Finnish Ayrshire bull with an incidence of almost 50% of late abortion/stillbirth in his progeny. A half-sib linkage analysis with the BovineSNP50 BeadChip implicated the maternally imprinted PEG3 domain on chromosome BTA18. Genes in this region are not expressed when inherited from the female parent. Close examination of this region disclosed that this bull was heterozygous for a 110 kb deletion in the MIMT1 gene. All of his offspring will have received a non-functional (maternally imprinted) version of this gene from their dam. The 50% of his offspring that receive the deletion from the bull will therefore have no functional MIMT1 gene. The vast majority of these offspring die in late pregnancy, resulting in late abortion/stillbirth. From a gene-expression study in affected and normal foetuses, Flisikowski et al. (2012) implicated a number of genes, especially NRSP1, which encodes neuropeptide S receptor 1.

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.
