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.
Comprehensive Coverage. 1  What is Comprehensive Insurance Coverage? When your vehicle is damaged as the result of an incident other than a collision, comprehensive insurance is an optional coverage that will pay the cost, minus your deductible, of repairing or replacing it. For example, you're covered if your vehicle sustains damage from a storm, a flood, a fire, vandalism, or theft.
