Case153: Female, 0.083 years onset, Japan, Asian
DiseaseAssertion: Left ventricular noncompaction
CasePresentingHPOs: HP:0030682, HP:0025169 (Left ventricular noncompaction, Left ventricular systolic dysfunction)
HPOsFreeText: Left Ventricular Ejection Fraction at 46%, LVDD-Z score at 0.795
CaseNotHPOs: HP:0011675 (Arrhythmia)
NotHPOsFreeText: Congenital heart disease with significant hemodynamic changes
CaseAddInfo: Sister also has LVNC
CasePreviousTesting: Genes tested include the 8 sarcomere genes as well as 65 more listed in Table S1.
CaseGenotypingMethod: Genomic DNA was extracted from whole blood from each of the probands. Next Generation Sequencing of 73 genes related to cardiac function was performed, incorporating PCR amplification, and any variants found were subjected to filtering for frequency and pathogenicity. Any variants suggested to be pathogenic were confirmed by Sanger sequencing afterwards.
