This condition varies in severity, from a severe, early-onset type to a milder, late-onset form. Early-onset LAMA2 -related muscular dystrophy is apparent at birth or within the first few months of life Collectively, complete and partial merosin deficiency is referred to as LAMA2-related dystrophies (LAMA2-RDs) and represents one of the most common forms of congenital muscular dystrophies worldwide
Mutations in the LAMA2 gene cause autosomal recessive laminin α2 related congenital muscular dystrophy. In patients with partial laminin α2 deficiency the phenotype is usually milder than in those with absent protein Introduction: LAMA2 Associated Muscular Dystrophy (LAMA2-RD) is one of the most common forms of congenital muscular dystrophy worldwide. Mutations in the LAMA2 gene affect the production of the α2 subunit of lamin-211 (merosine) and result in partial or complete deficiency of lamin-211. Inheritance is usually autosomal recessive
The clinical manifestations of LAMA2 muscular dystrophy (LAMA2-MD) comprise a continuous spectrum ranging from severe congenital muscular dystrophy type 1A (MDC1A) to milder late-onset LAMA2-MD. MDC1A is typically characterized by neonatal profound hypotonia, poor spontaneous movements, and respiratory failure Laminin-α2-related congenital muscular dystrophy (LAMA2-CMD) is a devastating neuromuscular disease caused by mutations in the LAMA2 gene. These mutations result in the complete absence or truncated expression of the laminin-α2 chain In a patient with congenital muscular dystrophy and partial LAMA2 deficiency (607855), Pegoraro et al. (2000) identified compound heterozygosity for 2 mutations in the LAMA2 gene: a 4694C-T transition in exon 31, resulting in an arg1549-to-ter (R1549X) substitution, and a 7196C-T transition in exon 49, resulting in an arg2383-to-ter (R2383X; 156225.0012) substitution LAMA2 MD — also called congenital MD type 1A — is caused by mutations in the gene LAMA2, which codes for the laminin-alpha 2 protein required to build muscle fibers
