The mutations found in the HD allele result in a protein that has normal activity. The pattern of inheritance of Huntington disease indicates that the HD disease allele is to the normal (HD") allele. If a mother is heterozygous for the normal and disease- causing HD alleles and a father is homozygous for the normal allele, it is all their children will have Huntington disease. Offspring of individuals that have only one parent with the mutant HD allele have a chance of having Huntington disease.

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
