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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.5332G>A (p.D1778N) alteration is located in exon 37 (coding exon 35) of the MYH1 gene. This alteration results from a G to A substitution at nucleotide position 5332, causing the aspartic acid (D) at amino acid position 1778 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
