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.
The five primary classes of immunoglobulins are IgG, IgM, IgA, IgD and IgE. These are distinguished by the type of heavy chain found in the molecule. IgG molecules have heavy chains known as gamma-chains; IgMs have mu-chains; IgAs have alpha-chains; IgEs have epsilon-chains; and IgDs have delta-chains.
