Scientists are reporting that a region on chromosome 9 is related to an increased risk of heart disease.
What gene is affected by heart disease?
The scientists combined all their data and came up with six genetic variants that were linked to heart attacks or heart disease. Those variants are in or near the MTHFD1L, PSRC1, MIA3, SMAD3, CDKN2A/CDKN2B, and CXCL12 genes.
What chromosome is congenital heart disease on?
Chromosomal aneuploidy, the first recognized genetic cause of CHD, continues to be a major etiology today (Table 1). CHD occurs in approximately 40–50% of trisomy 21 (1 in 600 births52), 20–50% of Turner syndrome (1 in 2500 female births53), and in almost all cases of both trisomy 13 and trisomy 18.
Is heart disease Y linked?
The human Y chromosome is associated with risk of coronary artery disease in men of European ancestry, possibly through interactions of immunity and inflammation.
Is heart disease a dominant or recessive trait?
Most genetic heart conditions are inherited in an autosomal dominant pattern. Autosomal means that both men and women are equally affected. Dominant means that although there are two copies of each gene, a mutation in just one copy is enough to cause disease.
What are the five risk factors for heart disease?

- High Blood Cholesterol. One of the major risk factors for heart disease is high blood cholesterol. …
- Diabetes. …
- Obesity and Overweight. …
- Smoking. …

Can you prevent hereditary heart disease?
Nutrition and diet
Maintaining a good diet can reduce your risk for heart disease. This is true even if you have a family history or genetic predisposition for heart disease. A diet high in raw fruits and vegetables, whole grains, and omega-3 fatty acids, which are often present in fish, helps prevent heart disease.
What is the life expectancy of someone with CHD?
About 75% of babies born with a critical CHD are expected to survive to one year of age. About 69% of babies born with critical CHDs are expected to survive to 18 years of age. Survival and medical care for babies with critical CHDs are improving.
What is the symptoms of congenital heart disease?
General signs of congenital heart disease can include:
- a blue tinge to the skin (cyanosis)
- rapid breathing.
- rapid heartbeat.
- swelling in the legs, tummy and around the eyes.
- shortness of breath in babies during feeding (making it hard for them to gain weight) and in older children and adults during exercise.
What is the most common cause of congenital heart disease?
Down’s syndrome is the most widely-known genetic condition that can cause congenital heart disease.
Will I have a heart attack if my dad did?
If your mom or dad had a heart attack, you might wonder if that’s going to happen to you, too. But your family’s history doesn’t have to become your future. You can do a lot to protect your ticker. It’s true that you’re more likely to get heart disease if it runs in your family.
What are the 4 stages of heart failure?
There are four stages of heart failure – stage A, B, C and D – which range from ‘high risk of developing heart failure’ to ‘advanced heart failure’.
What is considered a family history of heart disease?
A family history of heart disease is generally defined by having a first-degree male relative (i.e., father or brother) who had a heart attack by age 55, or a first-degree female relative (i.e., mother or sister) by age 65. Just as important, consider lifestyle changes that improve your heart health.
