Huntington’s disease is an autosomal dominant disorder and it has several
clinical symptoms such as jerking (involuntary) movements, muscle rigidity or
contracture, balance, posture, impaired gait, muscle problems, abnormal eye
movements. There are problems with motor speech and swallowing issues exists as
well. Overall, the symptoms can be divided into are muscle movement problems, eye
movement problems, muscle tone problems and speech problems which causes
immense problems in the activities of daily life as well as in the execution of motor
actions for daily day to day actions. As it is an autosomal dominant disorder, there are
very high chances that the genes can be inherited to the progeny, as there is no carrier
stage involved in the process (Craufurd, Thompson & Snowden, 2018). As
Huntington’s disease is an autosomal disease and just one of the partner has
Huntington’s disease and the other partner is normal, there are fifty per cent chances
that the progenies that their children might have or be affected with Huntington’s
disease (Benraiss et al. 2016). And if both the parents are having the genes for
Huntington’s, which means both of them are dominant, then all their children,
irrespective of genders will be Huntington’s dominant, which means they will have
the Huntington’s disease. It is to be noted that Huntington’s disease is not an
allosomal or an X-linked disease and the occurrence of the disease does not depend on
the genders of the children (Cubo et al., 2016). With someone with Huntington’s
disease, the family has to go through a lot of medical and nursing attention for that
individual and it is very important that the diagnosis of the disease is done from an
early stage so that the interventions can begin as soon as possible so that the cases are
managed in a pertinent manner. Family education and mental health counselling is
also required. Hence, genetic testing becomes a very important tool in order to
diagnose and assess the first stages and the second stages of Huntington’s disease.
