| Identified Mutation |
ARG2578TER |
| Remarks |
Clinically affected; symptom onset before 2 years of age; elevated creatine kinase (200-2,000 IU/L); diagnosis confirmed by muscle imaging and biopsy; abnormal white matter in brain by MRI/CT scan; head held up without assistance; turned in bed by age three years; no other milestones have been achieved; night time respiratory support; donor subject is a compound heterozygote: maternal allele has a 2 bp deletion in exon 14 of the LAMA2 gene (2049_2050delAG); the paternal allele has a C>T transition at nucleotide 7732 in exon 55 (7732C>T) resulting in a premature stop at codon 2578 [Arg2578Ter (R2578X)]. |
