Internet Medical Databases Gene Hunting


The constituent, GSM 1, is located on chromosome 9, on the long arm (q13-q21). The alias of the gene is GSP. The disease associated with this gene is geniospasm, comm and known as chin trembling. It is a inheritable disease transmitted as an autosomal dominant trait. A hereditary chin quiver or shake, that ass only be passed by a person with that trait. It may dupe a slight preference for males. Doctors must not blear the disease with other abnormalities, such as: facial myokymia, palatalized tremor, and essential tremor affecting facial muscles. It was first depict over 100 years ago, in 1894. It is characterized by paroxysmal, danceable quivering movements of the chin, due to involuntary contractions of the mentalis muscle. A geniospasm episode can last for a few seconds to a few hours. It is typically triggered by stress/anxiety, emotions, or the episode can have the appearance _or_ semblance to have an unknown cause. The diseases onset is in the early years of life, usually in the infant stage. The symptoms wait to subside as life progresses. The disease can be annoying, and embarrassing, but in that respect seems to be no harm do to the rest of the bodys nervous system. The affected individuals melodic theme being normal during the attacks. Also, tongue-biting during sleep is a common symptom.



Since there are no serious implications, it is probable that most patients never seek medical attention, therefore masking the true subdue of affected individuals. The neurophysiological and molecular mechanisms of this rare dis evidence are not known. However, the action of the muscle involved during the spasm is known. The mentalis muscle is innervated by the ipsilateral facial nerve nucleus in the brain stem. The bilateral movement, which affects most of the mentalis muscle, suggests that the problem stems from the mentalis muscle, or even off in the brain centers.
