Abstract/OtherAbstract:
The impact of molecular genetics in the diagnosis and management of various forms of heritable cardiac or vascular disorders is continuously increasing thanks to the newly available laboratory tools. Familial hypertrophic cardiomyopathy (FHC), an autosomal dominant inherited disease characterized by unexplained left ventricular hypertrophy and a wide range of clinical symptoms, is the first cardiac disorder whose genetic bases have been elucidated. Linkage analysis studies have shown a statistically significant association between the disease status and at least seven genetic loci, all coding for sarcomeric proteins, in unrelated kindreds. A major challenge for physicians is to make an accurate and early diagnosis, not only on the basis of the traditional tools (i.e. physical examination and electro-echocardiography) but also to focus on the impact of genotype on clinical manifestations of FHC. In this review we present the more recent findings on the genetic basis of FHC and analyze the genotype-phenotype correlations of this disorder, whose expression may be modulated by additional factors (modifier genes, genetic background, environmental factors) other than mutations in any of the sarcometric proteins.
