The purpose of this study is to better understand the genetic factors related to the Chiari I malformation. In people with this abnormality, the lower part of the skull is smaller than normal.andidates for this study are: 1) Patients with Chiari I malformation who also have a family member with the abnormality or a family member with syringomyelia (a cyst in the spinal cord that is often associated with the Chiari I malformation).
A hemoglobin electrophoresis test is a blood test used to measure and identify the different types of hemoglobin in your bloodstream. Hemoglobin is the protein inside red blood cells that is responsible for transporting oxygen throughout your circulatory system to your tissues and organs.he types of hemoglobin include: 1  hemoglobin F: This type is found in growing fetuses and newborns. 2  hemoglobin A: This is the most common type of hemoglobin found in healthy children and adults. 3  hemoglobin C, D, E, M, and S: These (and many other, rarer variations) are types of abnormal hemoglobin.
Hemoglobin S and hemoglobin C are the most common types of abnormal hemoglobin that may be found by an electrophoresis test. Electrophoresis uses an electrical current to separate normal and abnormal types of hemoglobin in the blood.Hemoglobin types have different electrical charges and move at different speeds. The amount of each hemoglobin type in the current is measured.n abnormal amount of normal hemoglobin or an abnormal type of hemoglobin in the blood may mean that a disease is present. Abnormal hemoglobin types may be present without any other symptoms, may cause mild diseases that do not have symptoms, or cause diseases that can be life-threatening.
