Year key variant first reported: 2010

Cross-species summary: Also known as X-linked myotubular myopathy (XLMTM)

Inheritance: Beggs et al. (2010) presented pedigree information that was inconsistent with autosomal recessive inheritance but consistent with X-linked recessive inheritance.

Molecular basis: Based on the close histopathological resemblance to human MTM1 (see link to MIM entry above), Beggs et al. (2010) sequenced all 15 exons of the comparative candidate MTM1 gene in two affected male Labrador Retrievers, one obligate female carrier Labrador Retriever, and several non-affected dogs from other breeds. A potentially causative missense mutation (c.465C>A; p.N155K) in exon 7 was confirmed by further sequencing ("seven affected males, representing each of the affected families, were found to be hemizygous for this change, whereas three obligate female carriers were all heterozygous") and genotyping (the mutation "was not seen in any of 237 unrelated and unaffected Labrador Retrievers from throughout North America, Europe, and Australia, nor was it detected in any of 59 additional control dogs from 25 other breeds"). Shelton et al. (2015) sequenced the same gene in a group of Australian Rottweilers segregating in a similar (X-linked) manner for very similar clinical signs, and discovered a different causal missense mutation (c.1151A>C; p.Q384P) in exon 11. Subsequent genotyping of this mutation in UK Rottweilers and other (unrelated) Australian Rottweliers showed no trace of the mutation, suggesting that this mutation is fairly new. In an affected male Boykin spaniel, Olby et al. (2020) identified a likely causal variant, namely "a premature stop codon in exon 13 of MTM1 (ChrX: 118,903,496 C > T, c.1467C>T, p.Arg512X). . . . The puppy's dam was heterozygous for the variant, and 3 male puppies from a subsequent litter all of which died by 2 weeks of age were hemizygous for the variant."

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

Breeds: Boykin Spaniel (Dog) (VBO_0200214), Labrador Retriever (Dog) (VBO_0200800), Rottweiler (Dog) (VBO_0201143).

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.
