OMIA:001450-9913 : Congenital muscular dystonia 1 in Bos taurus (taurine cattle)
Categories: Muscle phene
Links to MONDO diseases:
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2008
Species-specific symbol: CMD1
Species-specific description: In the words of Charlier et al. (2008), "All calves with CMD have episodes of generalized muscle contractures, but careful clinical examination suggested two distinct phenotypes (CMD1 and CMD2."
Mapping: In a pioneering use of tens of thousands of SNP markers ("using either the 25K Affymetrix SNP panel or a custom-made 60K Illumina panel"), Charlier et al. (2008) identified a single 2.12 Mb region on BTA25 in which 12 affected calves were significantly more homozygous for the same allele at each of many SNPs, when compared with 14 normal controls. An investigation of comparative candidate genes in this region identified six possible candidate genes. Sequencing revealed the causative molecular lesion in the ATPA2A1 gene, whose peptide is involved in calcium flow into the sarcoplasmic reticulum.
Molecular basis: "A missense mutation (C1676T) leading to a R559C substitution in exon 14 of ATP2A1" (Charlier et al., 2008)
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: "Calves affected by CMD1 show impaired swallowing, fatigue upon stimulation or exercise, and muscle myotonia resulting in an inability to flex limbs and injurious falling. CMD1 calves usually die within a few weeks as a result of respiratory complications." (Charlier et al. (2008)
Belgian Blue (Cattle) (VBO_0000139).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective.

order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
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.
