1 Compound Heterozygous: means you have one copy of the 677 mutation from one parent and one copy of the 1298 mutation from the other parent. 2  Triple homozygous mutations (more rare): an example would be one C677T, one A1298C, and a P39P or R594Q, for example.ore than one mutation of the MTHFR gene. Genes are passed down by your mother and your father. Most literature states there are a good 40-50 different mutations of this important gene which could be passed down by one, or both or your parents.
The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can't feel the liver, because it's protected by the rib cage. The liver has two large sections, called the right and the left lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines.
The liver is located in the upper part of the abdominal cavity just beneath the diaphragm. The greater part of the liver is situated under cover of the right costal margin and also extends to the left to reach the left hemidiaphragm. The diaphragm separates liver from pleura, lungs, pericardium and heart.
