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.
In vertebrates, these molecules are the proteins myoglobin and hemoglobin. Red blood cells (above) contain hemoglobin. Blood is bright red (left), due the presence of oxy-hemoglobin. Hemoglobin (or haemoglobin, frequently abbreviated as Hb), which is contained in red blood cells, serves as the oxygen carrier in blood. The name hemoglobin comes from heme and globin, since each subunit of hemoglobin is a globular protein with an embedded heme (or haem) group. Each heme group contains an iron atom, and this is responsible for the binding of oxygen. The presence of hemoglobin in blood increases the oxygen carrying ability of a litre of blood from 5 to 250 ml. Hemoglobin also plays a major role in the transport of carbon dioxide from the tissues back to the lungs.
