چکیده

conclusions bioinformatics analyses using sift, mutation taster and polyphen-2 indicated that p.ile563val was predicted to be damaging, disease causing, and probably damaging to and causing ldb3 dysfunction. as such, this mutation produces novel protein coding transcripts, which might explain the mfm phenotype in the patient. introduction myofibrillar myopathy (mfm) is a rare human disease, characterized by a distinct histopathological pattern of myofibrillar degeneration and protein aggregates. ldb3 protein encoded by this gene is a key z-disk protein that interacts with α-actinin and protein kinase c. case presentation in this paper, we identified the novel heterozygous, and hence, dominant mutation in the lim domain-binding protein 3 gene (ldb3) in a patient affected by myofibrillar myopathy (mfm). we performed direct sequencing in an iranian patient with autosomal-dominant inheritance of mfm characterized by clinical features, and we identified a heterozygous missense mutation in exon 10, c.1687a > g (p.ile563val) in the ldb3 gene on chromosome 10:88476524.

A novel dominant D109A CRYAB mutation in a family with myofibrillar myopathy affects αB-crystallin structure

Myofibrillar myopathy (MFM) is a group of inherited muscular disorders characterized by myofibrils dissolution and abnormal accumulation of degradation products. So far causative mutations have been identified in nine genes encoding Z-disk proteins, including αB-crystallin (CRYAB), a small heat shock protein (also called HSPB5). Here, we report a case study of a 63-year-old Polish female with a...

Novel autosomal dominant TNNT1 mutation causing nemaline myopathy

BACKGROUND Nemaline myopathy (NEM) is one of the three major forms of congenital myopathy and is characterized by diffuse muscle weakness, hypotonia, respiratory insufficiency, and the presence of nemaline rod structures on muscle biopsy. Mutations in troponin T1 (TNNT1) is 1 of 10 genes known to cause NEM. To date, only homozygous nonsense mutations or compound heterozygous truncating or inter...

Identification of a Novel Splice Site Mutation in RUNX2 Gene in a Family with Rare Autosomal Dominant Cleidocranial Dysplasia

Introduction: Pathogenic variants of RUNX2, a gene that encodes an osteoblast-specific transcription factor, have been shown as the cause of CCD, which is a rare hereditary skeletal and dental disorder with dominant mode of inheritance and a broad range of clinical variability. Due to the relative lack of clinical complications resulting in CCD, the medical diagnosis of this disorder is challen...
