"It is unclear why mutations in the filament-forming tail of myosin heavy chain (MHC) cause hypertrophic or dilated cardiomyopathy as these mutations should not directly affect contraction. To investigate this, we first investigated the impact of five hypertrophic cardiomyopathy-causing (N1327K, E1356K, R1382W, E1555K, and R1768K) and one dilated cardiomyopathy-causing (R1500W) tail mutations on their ability to incorporate into muscle sarcomeres in vivo."

Results suggest that small effects of mutations on helicity translate into a reduced ability to incorporate into sarcomeres, which may elicit compensatory hypertrophy.

DiseaseAssertion: Hypertrophic obstructive cardiomyopathy (HOCM) during clinical screening, presence of the familial mutation in the MYL2 gene MYL2, c.487G > A [p.(Glu163Lys) as pathogenic.

FamilyInfo: a family history of sarcomeric HCM who was diagnosed with hypertrophic obstructive cardiomyopathy (HOCM) during clinical screening. His father suffered from HCM and died 6 years ago in his 3rd decade due to a stroke. The paternal grandfather of the proband and his sister were also diagnosed with HCM. Other affected family members included a paternal uncle and his son as well as a paternal aunt and her son. Genetic testing of the latter family members revealed a mutation in the MYL2 gene.

ParentalTesting: Yes the family members

CasePresentingHPOs: HP:0034313, HP:0031666, HP:0001670

CaseHPOFreeText: He was well and asymptomatic. His weight was 44.6 kg (93rd centile) and height was 150.5 cm (94th centile); heart rate was 60 b.p.m. and right arm blood pressure was 111/67 mmHg with a mean arterial pressure of 83 mmHg. On auscultation, a 2/6 systolic murmur in the 3rd intercostal space at the left sternal edge was audible. N-terminal prohormone of brain natriuretic peptide level was 434 ng/L (normal range <112 ng/L). The echocardiogram showed asymmetric septal hypertrophy (maximal wall thickness 18 mm) of the left ventricle (LV) with mild flow acceleration in the mid-LV cavity (peak systolic velocity 2.6 m/s) consistent with HOCM. Left ventricle systolic function was hyperdynamic with LVEF of 80%. Late gadolinium enhancement (LGE) imaging showed an area of patchy LGE at the level of the maximal LV wall thickness (Figure 4).
