Cross-species summary:
Renamed from 'myoclonus' to 'hyperekplexia, GLRA1-related' [27/5/2023]
See also entries for 'OMIA:001594 : Hyperekplexia (Startle disease), SLC6A5-related'
Species-specific name: inherited myoclonus; congenital myoclonus; neuraxial (o)edema
Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous disorder in humans and mice), Pierce et al. (2001) identified a causal mutation as a "a cytidine to adenine transversion at position 156 of the Glra1 gene (156C>A). The 156A allele is predicted to substitute a termination codon for a tyrosine codon (Y24*) in exon 2 . . . This substitution is predicted to result in a prematurely truncated protein that lacks ligand-binding and membrane-spanning domains".
Breed:
Polled Hereford (Cattle) (VBO_0000341).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

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.
