Human molecular genetics involves the investigation of the structure and function of genes. Genes are the messangers of inheritance.
What is molecular genetics
To get a definition of "what is molecular genetics" we can go to the experts at the Canadian government who define it as
The study of the expression, regulation and inheritance of genes at the level of DNA and its transcription products.
For most people this does not help a great deal but we do know that those working in the field have an excellent understanding of "what is molecular genetics" and we can be reassured.
Human molecular genetics has brought us a long way in understanding heart disease inheritance and it will continue to do so in conjunction with other techniques such as the use of the human genome.
Where necessary our health care providers can use these tools to help diagnose and treat any heart disease problem we may encounter. However prevention is better than cure so if we could determine how likely we might be for such a heart complaint we may be able to seek help earlier.
If you can identify family members who are known to have had cardiovascular disease then you would be advised to consider performing a risk assessment for yourself This would enable you to identify any potential for your heart disease.
In the future medical science including human molecular genetics may be able to identify those of us at risk but in the meantime we need to be more self sufficient. |
