OMIA:001319-9913 : Myopathy of the diaphragmatic muscles in Bos taurus (taurine cattle)

Categories: Muscle phene

Possibly relevant human trait(s) and/or gene(s) (MIM number): 140550 (gene)

Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2003

Species-specific symbol: HMDM

Mapping: A genome scan with 1200 microsatellites enabled Sugimoto et al. (2003) to linkage map the HMDM locus to the bovine MHC on chromosome BTA23q21.

Molecular basis: From a BAC contig encompassing the candidate region of the bovine MHC (see Mapping section above), Sugimoto at al. (2003) determined that this disorder in Holstein-Friesian cattle is due to the deletion of one of two HSP70 (heat-shock protein) genes in the bovine major histocompatibility complex.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: "In normal diaphragmatic muscle, Hsp70 binds several proteins involved in energy metabolism including glycogen phosphorylase (PYGM). Immunohistochemical staining indicated that PYGM accumulated in the HMDM-specific core-like structures in affected cattle. Misfolding of energy-related proteins due to Hsp70 deficiency might lead to protein aggregation and muscle fibre degeneration." (Sugimoto at al., 2003)

Breed: Holstein Friesian (Cattle) (VBO_0000239).

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.
