CasePreviousTesting: See Table 1

CaseGenotypingMethod: DNA was isolated from peripheral blood. Most participants underwent testing from the Illumina Cardiomyopathy Sequencing Panel, which includes 46 cardiomyopathy related genes. For others, whole exome sequencing or Sanger squencing was used. After the results were returned, variants were filtered for pathogenicity and rarity.

Variant: NM_000257.3:c.1370T>C (p.Ile457Thr)

NotHPOsFreeText: N/A

CaseAddInfo:

CaseGenotypingMethod: DNA was collected from the participants using blood samples. 18 genes suspected on contributing to HCM were targeted and sequenced. The variants were then located and filtered for pathogenicity.
