[https://www.uniprot.org/uniprot/MYH7_HUMAN MYH7_HUMAN] Defects in MYH7 are the cause of familial hypertrophic cardiomyopathy type 1 (CMH1) [MIM:[https://omim.org/entry/192600 192600]. Familial hypertrophic cardiomyopathy is a hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death.<ref>PMID:1975517</ref> <ref>PMID:1417858</ref> <ref>PMID:1638703</ref> <ref>PMID:1552912</ref> <ref>PMID:8250038</ref> <ref>PMID:8343162</ref> <ref>PMID:8435239</ref> <ref>PMID:8268932</ref> <ref>PMID:8254035</ref> <ref>PMID:8483915</ref> <ref>PMID:7848441</ref> <ref>PMID:7874131</ref> <ref>PMID:8282798</ref> <ref>PMID:7581410</ref> <ref>PMID:7731997</ref> <ref>PMID:8655135</ref> <ref>PMID:8899546</ref> <ref>PMID:10065021</ref> <ref>PMID:9544842</ref> <ref>PMID:9829907</ref> <ref>PMID:9822100</ref> <ref>PMID:10521296</ref> <ref>PMID:10563488</ref> <ref>PMID:10329202</ref> <ref>PMID:10679957</ref> <ref>PMID:10862102</ref> <ref>PMID:11113006</ref> <ref>PMID:11214007</ref> <ref>PMID:11733062</ref> <ref>PMID:11424919</ref> <ref>PMID:11133230</ref> <ref>PMID:12081993</ref> <ref>PMID:11861413</ref> <ref>PMID:11968089</ref> <ref>PMID:12951062</ref> <ref>PMID:12566107</ref> <ref>PMID:12707239</ref> <ref>PMID:12974739</ref> <ref>PMID:12820698</ref> <ref>PMID:12975413</ref> <ref>PMID:12590187</ref> <ref>PMID:12818575</ref> <ref>PMID:15358028</ref> <ref>PMID:15563892</ref> <ref>PMID:15483641</ref> <ref>PMID:15858117</ref> <ref>PMID:16199542</ref> <ref>PMID:15856146</ref> <ref>PMID:16650083</ref> <ref>PMID:16938236</ref> <ref>PMID:17372140</ref> <ref>PMID:18403758</ref>   Defects in MYH7 are the cause of myopathy myosin storage (MYOMS) [MIM:[https://omim.org/entry/608358 608358]. In this disorder, muscle biopsy shows type 1 fiber predominance and increased interstitial fat and connective tissue. Inclusion bodies consisting of the beta cardiac myosin heavy chain are present in the majority of type 1 fibers, but not in type 2 fibers.<ref>PMID:14520662</ref> <ref>PMID:15136674</ref> <ref>PMID:17336526</ref>   Defects in MYH7 are the cause of scapuloperoneal myopathy MYH7-related (SPMM) [MIM:[https://omim.org/entry/181430 181430]; also known as scapuloperoneal syndrome myopathic type. SPMM is a progressive muscular atrophia beginning in the lower legs and affecting the shoulder region earlier and more severely than distal arm.<ref>PMID:17336526</ref>   Defects in MYH7 are a cause of cardiomyopathy dilated type 1S (CMD1S) [MIM:[https://omim.org/entry/613426 613426]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.<ref>PMID:11106718</ref> <ref>PMID:12379228</ref> <ref>PMID:15769782</ref> <ref>PMID:21846512</ref>   Defects in MYH7 are the cause of myopathy distal type 1 (MPD1) [MIM:[https://omim.org/entry/160500 160500]. MPD1 is a muscular disorder characterized by early-onset selective weakness of the great toe and ankle dorsiflexors, followed by weakness of the finger extensors. Mild proximal weakness occasionally develops years later after the onset of the disease.<ref>PMID:15322983</ref> <ref>PMID:17548557</ref> 
== Function ==
[https://www.uniprot.org/uniprot/GCN4_YEAST GCN4_YEAST] Is a transcription factor that is responsible for the activation of more than 30 genes required for amino acid or for purine biosynthesis in response to amino acid or purine starvation. Binds and recognize the DNA sequence: 5'-TGA[CG]TCA-3'.[https://www.uniprot.org/uniprot/MYH7_HUMAN MYH7_HUMAN] Muscle contraction.[https://www.uniprot.org/uniprot/GFP_AEQVI GFP_AEQVI] Energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca(2+)-activated photoprotein aequorin.
