The Comprehensive Hemophilia Treatment Center at Children's Hospital Medical Center of Cincinnati can perform genetic testing and counseling for Hemophilia. Hemophilia results from a defect in the genetic material of the body. Any part of the DNA that controls an inherited trait is called a gene. Examples of inherited traits are eye color, hair color and blood type.
Genes are present within the cell in packages called chromosomes.
Most of the body's cells contain a complete copy of chromosomes and their genes. X and Y. Males receive an X chromosome from their mother and a Y chromosome from their father. Females have two X chromosomes, one from each parent. The genes that control production of clotting factors VIII and IX are located in the X chromosome. Not all males with hemophilia have mothers who are carriers.
