Co přináší znalost
Knowing a genetic cause supports earlier heart monitoring and family screening, and for genes with a high arrhythmia risk such as LMNA, FLNC and RBM20 it informs decisions about rhythm monitoring and implantable defibrillators.
Limb-Girdle Muscular Dystrophy
Limb-girdle Muscular Dystrophy is defined as a collection of numerous subtypes with differing inheritance patterns (with diagnostic sufficiency being varied too). Carriers of variants related to the condition should seek guidance from a muscular-skeletal specialist for a definitive diagnosis.

Dědičnost
- Autozomálně dominantní
- Stačí jedna změněná kopie od kteréhokoli z rodičů. Rodič, který ji má, ji předá každému dítěti s pravděpodobností jedna ku dvěma.
- Autozomálně recesivní
- Je potřeba změněná kopie od každého z rodičů. S jednou kopií jste nositelem a obvykle nejste postiženi; pokud jsou oba rodiče nositeli, má každé dítě pravděpodobnost jedna ku čtyřem, že zdědí dvě.
