In affected members of a large family with Emery-Dreifuss muscular dystrophy-6 (EDMD6; see 300696), Gueneau et al. (2009) identified a 625C-T transition in exon 6 of the FHL1 gene, resulting in a cys209-to-arg (C209R) substitution affecting a highly conserved cys residue of the LIM3 domain of the FHL1A and FHL1B isoforms. The proband presented at age 11 years with stiff neck. He later developed scapular and pelvic muscle weakness and atrophy, multiple joint contractures, scoliosis, and increased serum creatine kinase. At age 39, he had cardiac arrhythmias and cardiac hypertrophy; He died suddenly at age 51. Most affected family members had both cardiac disease and myopathy, although some had only isolated cardiac disease or myopathy. There were several affected females who were heterozygous for the mutation. Skeletal muscle biopsy of the proband showed a dystrophic pattern and moderately decreased FHL1 protein expression.

Knoblauch et al. (2010) identified the C209R mutation in 9 affected male members of a large 4-generation German family with EDMD6. Age at onset was in the first or second decade, and all had contractures and rigid spine. Five had hypertrophic cardiomyopathy, 2 had left ventricular hypertrophy with fibrosis and hypertension, 1 had apical myocardial thinning, and 1 had normal cardiac findings. Only 1 had conduction abnormalities, and only 1 had clear muscle weakness; most appeared muscular but not athletic. Two female carriers of the mutation had rigid spine symptoms, and 1 had left ventricular hypertrophy with hypertension. None of the patients was or became wheelchair-bound. Skeletal muscle biopsy from 3 patients showed cytoplasmic bodies, but not reducing bodies, and dystrophic features. Western blot analysis showed decreased expression of FHL1.
