Abstract
Familial hypertrophic cardiomyopathy (FHC) is caused by missense mutations in the β cardiac myosin heavy chain (MHC) gene in less than half of affected individuals. To identify the location of another gene involved in this disorder, a large family with FHC not linked to the β MHC gene was studied. Linkage was detected between the disease in this family and a locus on chromosome 1q3 (maximum multipoint lod score = 8.47). Analyses in other families with FHC not linked to the β MHC gene, revealed linkage to the chromosome 1 locus in two and excluded linkage in six. Thus mutations in at least three genetic loci can cause FHC. Three sarcomeric contractile proteins — troponin I, tropomyosin and actin — are strong candidate FHC genes at the chromosome 1 locus.
