Genes affected

MYH1 (HGNC:7567): (myosin heavy chain 1) Myosin is a major contractile protein which converts chemical energy into mechanical energy through the hydrolysis of ATP. Myosin is a hexameric protein composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. Myosin heavy chains are encoded by a multigene family. In mammals at least 10 different myosin heavy chain (MYH) isoforms have been described from striated, smooth, and nonmuscle cells. These isoforms show expression that is spatially and temporally regulated during development. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 09, 2021

The c.5183T>C (p.I1728T) alteration is located in exon 36 (coding exon 34) of the MYH1 gene. This alteration results from a T to C substitution at nucleotide position 5183, causing the isoleucine (I) at amino acid position 1728 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
