Abstract

International audience; Background and purposeThe aim was to determine the genetic background of unknown muscular dystrophy in five French families.MethodsTwelve patients with limb girdle muscular dystrophy or distal myopathy were clinically evaluated. Gene mutations were identified using targeted exon sequencing and mutated DNAJB6 was tested invitro.ResultsFive patients presented with distal lower limb weakness whilst others had proximal presentation with a variable rate of progression starting at the mean age of 38.5years. Two novel mutations (c.284A>T, p.Asn95Ile, two families; and c.293_295delATG, p.Asp98del, one family) as well as the previously reported c.279C>G (p.Phe93Leu, two families) mutation in DNAJB6 were identified. All showed a reduced capacity to prevent protein aggregation.ConclusionsThe mutational and phenotypical spectrum of DNAJB6-caused muscle disease is larger than previously reported, including also dysphagia. The originally reported c.279C>G (p.Phe93Leu) mutation is now identified in four different populations and appears to be a mutational hotspot. Our report confirms that some DNAJB6 mutations cause distal-onset myopathy and hence DNAJB6 defects should be considered broadly in dominant muscular dystrophy families.

Abstract

Background and purpose We have previously reported clinical, genetic and molecular pathomechanistic findings in DNAJB6 mutated LGMD1D. After publishing clinical findings of the original Finnish family we identified more Finnish, Italian and US families with the same disease, ultimately confirmed by mutations in the same gene. Methods Of the total number of 28 examined Finnish and Italian patients 23 underwent lower limb muscle imaging. Results At the early stages of the disease fatty degeneration in T1-weighed MRI sequences were observed in the soleus, adductor magnus, semimembranosus and biceps femoris muscles followed by medial gastrocnemius, adductor longus and later by vasti muscles of the quadriceps. Rectus femoris, lateral gastrocnemius, sartorius, gracilis and the anterolateral group of the lower leg muscles were spared until late senecence. The pattern of differential involvement could be identified at different stages of the disease process. Conclusions Since the general clinical findings do not provide clues for diagnosis this distinct pattern of muscle involvement and pathognomonic imaging findings are highly relevant in the clinical setting. The pattern of muscle involvement is so typical that it can be used as a differential diagnostic tool for LGMD1D. The final diagnosis however requires molecular genetic confirmation.

Abstract

Background and purpose The aim was to identify potential genetic risk factors associated with sporadic inclusion body myositis (sIBM). Methods An association based case-control approach was utilized on whole exome sequencing data of 30 Finnish sIBM patients and a control cohort (n = 193). A separate Italian cohort of sIBM patients (n = 12) was used for evaluation of the results. Results Seven single nucleotide polymorphisms were identified in five genes that have a considerably higher observed frequency in Finnish sIBM patients compared to the control population, and the previous association of the genetic human leukocyte antigen region was confirmed. Conclusions All seven identified variants could individually or in combination increase the susceptibility for sIBM.
