Summaries for TNNT1 Gene

Entrez Gene Summary for TNNT1 Gene

  • This gene encodes a protein that is a subunit of troponin, which is a regulatory complex located on the thin filament of the sarcomere. This complex regulates striated muscle contraction in response to fluctuations in intracellular calcium concentration. This complex is composed of three subunits: troponin C, which binds calcium, troponin T, which binds tropomyosin, and troponin I, which is an inhibitory subunit. This protein is the slow skeletal troponin T subunit. Mutations in this gene cause nemaline myopathy type 5, also known as Amish nemaline myopathy, a neuromuscular disorder characterized by muscle weakness and rod-shaped, or nemaline, inclusions in skeletal muscle fibers which affects infants, resulting in death due to respiratory insufficiency, usually in the second year. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for TNNT1 Gene

TNNT1 (Troponin T1, Slow Skeletal Type) is a Protein Coding gene. Diseases associated with TNNT1 include Nemaline Myopathy 5 and Nemaline Myopathy. Among its related pathways are Cardiac conduction and Striated Muscle Contraction. Gene Ontology (GO) annotations related to this gene include tropomyosin binding and troponin T binding. An important paralog of this gene is TNNT2.

  • Nemaline myopathy 5 (NEM5) [MIM:605355]: A form of nemaline myopathy. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-like or rod-shaped structures in muscle fibers on histologic examination. Nemaline myopathy type 5 is a severe and progressive form common among Old Order Amish. Affected infants display tremors with hypotonia and mild contractures of the shoulders and hips. Proximal contractures progressively weaken and a pectus carinatum deformity develops before children die of respiratory insufficiency, usually in the second year. {ECO:0000269 PubMed:10952871}. Note=The disease is caused by mutations affecting the gene represented in this entry.
