In a genetic study of an early onset form of heart disease, a marker on chromosome 8 was found to be associated with the disease in six out of ten families. Analysis of the marker produced a lod score of 1.9. What do these findings suggest about the marker?

The marker is strongly associated with the disease

The marker is not associated with the disease

The marker is weakly associated with the disease

The marker may be associated with the disease, but further studies are needed to confirm the association
