Objective: To determine the phenotype variability associated with the specific C-terminal M-line titin mutation known to cause autosomal dominant distal myopathy, tibial muscular dystrophy (TMD; MIM 600334), and limb girdle muscular dystrophy 2J (LGMD2J). Methods: Three hundred eighty-six individuals were genotyped for the Finnish founder mutation in titin (FINmaj) causing TMD/LGMD2J. Results: Two hundred seven patients were heterozygous for the mutation. Among these patients, 189 (91%) had a…

Targeted Next-Generation Sequencing Reveals Novel TTN Mutations Causing Recessive Distal Titinopathy
TLDR
Targeted next-generation sequencing of myopathy-related genes on seven families from Albania, Bosnia, Iran, Tunisia, Belgium, and Spain with juvenile or early adult onset recessive distal myopathy with novel mutations in TTN Mex5, Mex6 and A-band exon 340 identified in homozygosity or compound heterozygosity with a frameshift or nonsense mutation in TTn I- or A- band region.
Myopathies caused by homozygous titin mutations: limb-girdle muscular dystrophy 2J and variations of phenotype
TLDR
A French family with an autosomal-dominant late-onset distal myopathy of the tibial muscular dystrophy phenotype segregating in several members of the family was described and the early phenotype in a newly identified young patient with homozygous Finnish C-terminal titin mutation (FINmaj) was detailed.
A ‘second truncation’ in TTN causes early onset recessive muscular dystrophy
Titin mutation segregates with hereditary myopathy with early respiratory failure.
TLDR
This disease should be considered in patients with adult-onset proximal or distal myopathy and early respiratory failure, even in the presence of non-specific muscle pathology, and if positive should prompt screening for mutations in TTN.
The first Italian family with tibial muscular dystrophy caused by a novel titin mutation
TLDR
Since the introduction of a proline in the last domain of titin was previously known to cause TMD in French families, it can conclude that this missense mutation is the obvious pathogenetic mutation in the affected patients.
Distal myopathy caused by homozygous missense mutations in the nebulin gene.
TLDR
It is concluded that homozygous missense mutations in NEB cause a novel distal myopathy, predominantly involving lower leg extensor muscles, finger extensors and neck flexors, which differs from NM in that nemaline bodies were not detectable with routine light microscopy, and they were inconspicuous or absent even with electron microscopy.
Titinopathies: what happens when a big gene mutates in a big family?
TLDR
In this issue of Neurology, Udd et al.1 add another chapter to the evolving story of titinopathies by investigating the skeletal muscle disease that is now also known to be a titinopathy in a multigeneration consanguineous family off the west coast of Finland.
Removal of the calpain 3 protease reverses the myopathology in a mouse model for titinopathies.
TLDR
By crossing the FINmaj model with a calpain 3-deficient model, the TMD phenotype was corrected, demonstrating a participation of cal pain 3 in the pathogenesis of this disease.

Tibial muscular dystrophy is a titinopathy caused by mutations in TTN, the gene encoding the giant skeletal-muscle protein titin.
TLDR
Immunohistochemical analysis using two exon-specific antibodies directed to the M-line region of titin demonstrated the specific loss of carboxy-terminal titin epitopes in the TMD muscle samples that were studied, thus implicating a functional defect of theM-line titin in the genesis of the T MD disease phenotype.
Assignment of the tibial muscular dystrophy locus to chromosome 2q31.
TLDR
The disease locus that was found represents a novel muscular dystrophy locus, providing evidence for the involvement of one additional gene in the distal myopathy group of muscle disorders.
The muscular dystrophy with myositis (mdm) mouse mutation disrupts a skeletal muscle-specific domain of titin.
TLDR
The Ttn(mdm) mutant mouse may serve as a model for human tibial muscular dystrophy, which maps to the TTN locus at 2q31 and shows a secondary reduction of CAPN3 similar to that observed in mdm skeletal muscle.
Autosomal dominant myopathy with proximal weakness and early respiratory muscle involvement maps to chromosome 2q.
TLDR
Two Swedish families with autosomal dominant myopathy, who also had proximal weakness, early respiratory failure, and characteristic cytoplasmic bodies in the affected muscle biopsies, were screened for linkage by means of the human genome screening set, and haplotype analysis indicated that the gene responsible for the disease is likely to be located in the 17-cM region.
Muscular dystrophy with separate clinical phenotypes in a large family
TLDR
The overall difference in clinical findings between these main variants would suggest 2 separate genetic entities, genealogical data makes a common genetic background possible.
Tibial muscular dystrophy in a Belgian family
TLDR
A Belgian family with autosomal dominant, late‐onset, distal myopathy with selective foot extensor muscle involvement of the lower legs and a disease‐specific, heterozygous point mutation in the last exon, Mex6, of the titin gene is reported, suggesting that titinopathies may occur in various populations.
Tibial muscular dystrophy. Late adult-onset distal myopathy in 66 Finnish patients.
TLDR
Tibial muscular dystrophy might represent a new form of distal myopathy and it is rather common, at least in Finland, and Pedigree data suggest autosomal dominant inheritance.
Mutations of TTN, encoding the giant muscle filament titin, cause familial dilated cardiomyopathy
TLDR
It is shown that mutations in the gene encoding giant-muscle filament titin (TTN) cause autosomal dominant DCM linked to chromosome 2q31 (CMD1G; MIM 604145), and the identification of TTN mutations in individuals with C MD1G should provide further insights into the pathogenesis of familial forms of CHF and myofibrillar titin turnover.
Titin mutations as the molecular basis for dilated cardiomyopathy.
TLDR
Observations suggest that titin mutations may cause DCM in a subset of the patients, and one of them was a nonsense mutation presumably encoding for a truncated nonfunctional molecule.
