Splet03. feb. 2024 · We report a case of neonatal nemaline myopathy with a de novo TPM3 mutation, which has been classified as a likely pathogenic mutation. With the expanding … SpletCap myopathy is a disorder that primarily affects skeletal muscles, which are muscles that the body uses for movement. People with cap myopathy have muscle weakness (myopathy) and poor muscle tone (hypotonia) throughout the body, but they are most severely affected in the muscles of the face, neck, and limbs.

( A) ATPase pH 4.6 stained muscle cross section of one control and four patients with mutations at residue R168, of α-TPM slow demonstrating a selective hypotrophy of slow type-1 myofibres.
The TPM3 gene provides instructions for making a protein called slow muscle alpha (α)-tropomyosin, which is part of the tropomyosin protein family. Tropomyosin proteins regulate the tensing of muscle fibers (muscle contraction) by controlling the binding of two muscle proteins, myosin and actin.
