Study of pathogenic genes in a pedigree with familial dilated cardiomyopathy

Table 1 Clinical situation of dilated cardiomyopathy patients in the family

Pedigree number	Age	Gender	Age of first episode	LVDD (mm)	EF	Arrythmia
I-1	60 (death)	Male	-	-	-	-
II-1	63 (death)	Male	-	-	-	-
II-2	67	Male	-	57	74	Tachyarrhythmia
II-3	62	Male	47	67	23	Occasional premature beat
II-4	60	Male	53	72	46	Occasional premature beat
II-7	64	Female	58	60	45	Normal

Normal value of left ventricular diastolic dysfunction range: 45-55 mm (male), 35-50 mm (female). Normal value of ejection fraction range: 50%-70%. LVDD: Left ventricular diastolic dysfunction; EF: Ejection fraction.
