Genes linked to Myocarditis
MYH7: Myosin-7
Its beta-myosin motor converts ATP hydrolysis into force within cardiac and slow-skeletal-muscle sarcomeres. Pathogenic variants are major causes of hypertrophic and dilated cardiomyopathy and can also produce inherited skeletal myopathies.
1 disease-causing and 0 uncertain variants in MYH7 are linked to Myocarditis.
Weakly linked (only a few uncertain records): LMNA, TNNT2, BAG3, TNNI3 and TTR.
Known disease-causing variants in Myocarditis
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| MYH7 T215I | 215 | Myosin motor | Disease-causing (★★) |
Same protein, different disease
- Hypertrophic cardiomyopathy is also caused by MYH7 variants; they fall mostly in different places as the Myocarditis variants (239 disease-causing).
- Dilated cardiomyopathy is also caused by MYH7 variants; they fall mostly in different places as the Myocarditis variants (21 disease-causing).
- Primary dilated cardiomyopathy is also caused by MYH7 variants; they fall mostly in different places as the Myocarditis variants (15 disease-causing).
- Myosin storage myopathy is also caused by MYH7 variants; they fall mostly in different places as the Myocarditis variants (13 disease-causing).
- MYH7-related skeletal myopathy is also caused by MYH7 variants; they fall mostly in different places as the Myocarditis variants (7 disease-causing).

Frequently asked questions
Which genes are linked to Myocarditis?
In CATVariant, Myocarditis is linked to 1 analyzed protein: MYH7 (Myosin-7).
How many genetic variants are linked to Myocarditis?
8 variants: 1 are classified as disease-causing (pathogenic or likely pathogenic) in ClinVar and 5 are of uncertain significance or have conflicting reports.
Which uncertain variants in Myocarditis look disease-causing?
None of the uncertain variants currently reaches the likely-pathogenic range on computable evidence alone.
About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
