Differentiation of hereditary HCM associated with mutations in sarcomeric genes from phenocopies (i.e. The testing will focus on seven genes associated with PD, including some that can be dormant and passed down to future generations. Genetic testing is also used to confirm if certain diseases are present once someone begins to show symptoms to confirm or refute a doctor’s diagnosis. The genetic heterogeneity associated with these conditions can make it difficult to use phenotype as the sole criterion to select a definitive cause.
