Target disease:
Effect type:
Expressivity
Modifier effect:
Risk factor
Evidence:
For noncarriers of polymorphic col1a1 allele [HR=2.76, 95% CI: (1.26-6.05), P=0.011] and a trend in homozygous carriers of adrb1 arg389 variant [HR=1.98, 95% CI:(1.99-4.02); P=0.057]
Effect:
COL1A1 polymorphism (2046G>T) is an independent predictor of prognosis in HCM patients supporting the importance of nonsarcomeric genes on clinical prognosis in HCM.
Abstract:
Hypertrophic cardiomyopathy (HCM) is characterized by cardiomyocyte hypertrophy and fibrosis. Although is an autosomal dominant trait, a group of nonsarcomeric genes have been postulated as modifiers of the phenotypic heterogeneity.
