OMIA 001621-9685 : Muscular dystrophy-dystroglycanopathy (limb-girdle) in Felis catus

In other species: chicken

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2015

Inheritance: Robinson (1992) provided evidence of autosomal recessive inheritance.

Molecular basis: Martin et al. (2008) reported a deficiency of alpha-dystroglycan in affected cats but could find no causative mutation in the DAG1 gene that encodes this peptide.

Gandolfi et al. (2015) and Abitbol et al. (2015) both reported a missense mutation (c.1190G>A; p.Cys397Tyr) as a likely causal variant in Sphynx and Devon Rex cats.

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.
