| pubmed-article:9001794 | pubmed:abstractText | Counselling and clinical assessment in familial hypertrophic cardiomyopathy (FHC) is difficult, particularly in the young, since echocardiographic and ECG changes may not be diagnostic and clinical severity can vary. From 1990, when the beta-cardiac myosin heavy chain gene was implicated in the aetiology of FHC, considerable information about the molecular genetics of this disorder has emerged. However, an important question facing health professionals is the practical significance of DNA testing in FHC. The present study describes a DNA-based approach to screening for five commonly reported mutations involving the beta-cardiac myosin heavy chain gene. Approximately 11% of randomly selected families had an abnormality detected. | lld:pubmed |
