What are the types of homocystinuria?

Classical Homocystinuria is divided into two types; Vitamin B6 responsive and Vitamin B6 non-responsive. This will be discussed more later. The second route of Homocysteine metabolism is the Remethylation Pathway that depends on Folate, a B vitamin. This pathway converts Homocysteine back to Methionine.

What deficiency causes homocystinuria?

In most cases, homocystinuria is caused by reduced activity of an enzyme known as cystathionine beta-synthase and this results in CBS deficiency.

What happens when homocysteine levels go above normal?

Like other health complications and disorders, Hyperhomocysteinemia is a critical vascular disorder that happens when the level of homocysteine in the human blood goes above normal values . It may react with other natural substances and create more complicated and lasting effects that are also hard to treat and recover. However, the excessive increase in the level of homocysteine will affect the vitamin-b complex family. This disorder itself does not cause any life threatening condition but it may produce some troublesome complications like increase risk of bone fractures and peripheral circulatory problems. This disorder can also lead to many vascular and cardiac issues. In general, Hyperhomocysteinemia directly influences and disturbs the arterial system and blood flow.

Why is homocysteine important?

Basically, the homocysteine is very important, fundamental and key substance for the growth of bones, muscles, tissues, vascular, and other body parts. The deficiency or increase in production of homocysteine may arise troublesome complications some which are irreversible.

What supplements are good for hyperhomocysteinemia?

The Vitamin B6, B9 & B12 supplements are the best to treat this medical condition. However, clinically there is no licensed treatment for hyperhomocysteinemia that is specifically designated for its treatment. People who have genetic predispositions towards hyperhomocysteinemia must avoid those actors that aggravate the level of homocysteine. As mentioned earlier only vitamins therapy is found to be beneficial in maintaining homocystein level so far. Many herbal alternatives are claimed to be effective in hyperhomocysteinemia but unfortunately non them is approved by US FDA.

Is homocysteine good for you?

The homocysteine is good for overall human health and this amino acid plays a key part to develop the tissues, muscles, bones and the bone mass. If there is any disturbance or deficiency, then the human body may suffer from critical problems. Similarly, if you observe the increase in amount or level of homocysteine in the blood, then more chronic infections and disorders will happen. However, there are very limited hyperhomocysteinemia symptoms which you can observe or come to know through medical checkups for the confirmation of this health condition. Some major signs of this disorder will be;

How is homocysteine formed?

Homocysteine (Hcy), a sulphur-containing amino acid, is formed from the conversion of methionine into cysteine. It is usually rapidly metabolized via 1 of 2 pathways:

What is the cause of homocystinuria?

The most common form of homocystinuria is caused by the lack of cystathionine beta-synthase (CBS), a vitamin B6-dependent enzyme. Homocystinuria caused by CBS deficiency affects at least 1 in 200,000 to 335,000 people worldwide. Other forms of homocystinuria are much rarer. Moreover, the hallmarks of homocystinuria caused by CBS deficiency are developmental delay/mental retardation, ectopia lentis (dislocation of the ocular lens) and/or severe myopia, skeletal abnormalities as well as thrombo-embolism. There are two phenotypic variants of homocystinuria:

What is the name of the amino acid that is formed from the conversion of methionine into cysteine?

Does HCY cause stroke?

While Hcy has been reported to exhibit atherogenic and prothrombotic properties, and histopathological hallmarks of Hcy-induced vascular injury include intimal thickening, elastic lamina disruption, smooth muscle hypertrophy, marked platelet accumulation, and the formation of platelet-enriched occlusive thrombi, its role in coronary heart disease and stroke is unclear. In randomized trials, reduction in Hcy levels has failed to lower overall risk for cardiovascular disease (CVD).
