And we found positive selection on chromosome 2 for the SMYD1 gene associated with hypertrophic cardiomyopathy stability [34] and the potassium channel arrhythmia-associated gene KCNJ3. We also screened for its overexpression on chromosome 4 related to the cancer gene PALLD [35]. The gene discussed is KCNJ3; the disease is hypertrophic cardiomyopathy.
