OMIA:001619-9685 : Muscular dystrophy, congenital merosin-deficient in Felis catus (domestic cat)

Categories: Muscle phene

Possibly relevant human trait(s) and/or gene(s) (MIM number): 607855 (trait)

Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal

Considered a defect: yes

Key variant known: no

Molecular basis: O'Brien et al. (2001) reported a deficiency of laminin alpha 2 (also called merosin) in affected cats. Presumably this is due to lack of expression of the LAMA2 gene.

Breeds: Devon Rex (Cat) (VBO_0100084), Maine Coon (Cat) (VBO_0100154), Sphynx (Cat) (VBO_0100230).
Breeds in which the phene has been documented. For breeds in which a likely causal variant has been documented, see the variant table below
