When a person has two copies of the MTHFR C677T gene mutation (homozygous) or one copy of MTHFR C677T and one copy of A1298C (compound heterozygous), decreased MTHFR enzyme activity slows down the homocysteine-to-methionine conversion process and can lead to a buildup of homocysteine in the blood.
Collision Coverage. When your insured vehicle overturns or collides with another object, Collision coverage pays for the damage to your vehicle. Collision coverage also may extend to a non-owned vehicle or one rented for personal use that is in your custody or that you are operating.
Collision vs. Comprehensive Coverage. Collision Insurance is an optional coverage that will pay for the cost of repairs up to a total loss, in which case Liberty Mutual will give you the cash value of the vehicle. Including it on your policy requires the purchase of comprehensive coverage.
