As you know everything in the human body is controlled by genes. Genes are composed of nitrogenous base pairs which are coded in pairs of three know as codons. Each set of three base pairs then codes for a specific amino acid which tells the body how to function. When a mutation occurs and extra nucleotide can be added or a nucleotide can be deleted which throws off the entire sequence of DNA

ex: AUGCUUGUCCCCUGGAAAAGGUUAGGCCAUUGA
(normal strand of DNA)

if an extra base pair is added lets say in the 15 place in the DNA sequence it causes the amino acid chain to terminate

ex: AUGCUUGUCCCCUGA

the reason for this termination is that the insertion of an adenine base changed the particular amino acid to a stop codon. The three stop codons have been given names: UAG is amber, UGA is opal (sometimes also called umber), and UAA is ochre. When DNA polymerase and enzyme that proofreads DNA stands sees this particular amino acids it terminates the base pairing causing the polypeptide chain to be too short to function. While this stand is thrown out of whack it can have a domino effect on other cells in the body. Causing other bodily systems to act unnaturally.

Mutations may alter an amount of something you need, like maybe a mutation causes your heart to pump less blood or something (I'm not sure if that's possible) but your body needs a lot of blood to survive and other organs need the blood to process so it could provide less of something for other body systems.

Not all gene mutations are bad, some might improve other body systems.

And do you mean lack of hemoglobin? Or the mutation? Because if you mean the mutation, then since hemoglobin causes wounds to not heal, then that could affect your body by maybe affecting the immune system; bacteria can enter the wound and attack the immune system. What if the immune system can't fight off the pathogen? Also, your cells won't get enough oxygen, since blood carries oxygen and their's a wound (circulatory system I believe...).

Hope I helped >.<

Hemoglobin is a protein that is contained interior of our pink blood cells. It includes oxygen. you are able to imagine a mutation that can make hemoglobin carry on to oxygen more advantageous tightly. each and each and every of the tissues of the body that get carry of oxygen from the circulatory equipment might want to grow to be oxygen starved, if the guy (or organism) might want to ensue to visit Denver, the position the elevation is severe and the air is particularly thinner.

an excellent example is sickle cell anemia. it is a mutation affecting the beta chain of the hemoglobin molecule. it tends to polymerize into rod-like shapes, causing the cells to sickle. these cells cannot move as easily through the smaller blood vessels of the body. one of the first organs affected is the spleen. the cells get trapped and cannot move into the tiny blood vessels in the spleen, and as a result, the spleen shrinks and no longer works. this is referred to as autosplenectomy. next, the joints will be affected, causing tremendous pain and difficulty in walking. the blood vessels of the kidney can also be deprived of blood, causing renal problems. as all of these sickle cells hemolyze because of their defects, the liver has to work overtime, and cannot keep up with the extra work, and bilirubin (a breakdown product of hemoglobin) increases in the bloodstream, causing jaundice and other problems. the heart can be severely affected since its blood supply is vital to its operation. the really fun part is the PAIN. patients have been known to suffer fatal heart attacks (myocardial infarctions) due to the severity of the pain.

gene mutations need to be dealt with very seriously a mutation in hemoglobin depending on how big of a mutation it is could shut down your circulatory and respiratory system and sometimes even your digestive system which is why radiation poisoning and meningitis are so deadly
