Explanation:
Lesch-Nyhan syndrome is a genetically transferred disorder caused by lack of hypoxanthine-guaninephosphoribosyltransferase (HGPRT). The lack of HGHPRT is caused when mutation happens in the HPRT1 gene in the X chromosome.
It is a very rare disorder usually inherited from the parents or the family tree . A person suffering from Lesch-Nyhan syndrome is commonly characterized by the overproduction of uric acid in their bodies.
Due to overproduction of uric acid, symptoms of Lesch-Nyhan syndrome include involuntary movements and self-mutilation. These abnormal movements include muscle movements such dystonia chorea, and ballismus.
