It is becoming evident that clinical phenotypes associated with partial laminin alpha2 chain deficiency are variable. We recently observed a 29-year-old man with leukoencephalopathy and vacuolar myopathy resembling inclusion body myositis. Laminin alpha2 immunohistochemical analysis showed reduction of the protein on muscle fiber surfaces. Molecular analysis revealed two novel compound heterozygous mutations in the LAMA2 gene. This is the first report linking a mutation in the LaMA2 gene with leukoencephalopathy and inclusion body-like myositis.
