Which of the following is true regarding homocysteinemia?

It is caused by a mutation in the 3' UTR of the cystathione β-synthetase gene

Acquired homocysteinemia can occur following deficiencies in vitamins B6, B12 and folic acid

A mutation within the cystathione β-synthetase gene results in decreased homocysteine metabolites and therefore decreased protein C synthesis

Defects within the cystathione β-synthetase gene result in fibrinogen which is more resistant to thrombin activation
