Lesch-Nyhan syndrome(LNS) is a congenital X-linked recessive inherited disorder caused by mutations in the hypoxanthine guanine phosphoribosyl transferase (HPRT) gene.A deficiency of the HPRT enzyme is responsible for the disease.The main clinical manifestation includes hyperuricemia, juvenile-onset gouty arthritis and neurological developmental disorders.Studies have reported there are more than 400 HPRT gene mutation sites, but the incidence of LNS in the Chinese population is extremely low.Here we report a 16-year-old male patient who suffered neurological dysfunction at an early age and gouty arthritis in his youth.DNA of patient and his family members were extracted from peripheral blood lymphocytes.The coding region and the intron-exon boundaries of HPRT gene were sequenced by standard methods.We found a mutation in exon 3 of the HPRT gene of the patient and his mother (Exon3:c.143G>A), which resulted in an arginine to histidine (p.R48H) substitution in the encoded protein.No activity of the enzyme HPRT was detected in the erythrocytes.The same mutation was reported in several European families, but was found in Chinese family for the first time.Clinicians in China have poor experience in diagnosing LNS case, due to the low incidence in China.Therefore LNS screening for infants or adolescents with hyperuricemia, gouty arthritis and neurological dysfunction should be performed.
