Abstract excerpt
Complete deficiency of hypoxanthine guanine phosphoribosyltransferase (HPRT) causes Lesch-Nyhan syndrome. We examined the HPRT gene mutation for prenatal diagnosis in a Japanese family. A single nucleotide substitution of C to T in exon 3 was identified by direct sequencing analysis of the HPRT gene of a Lesch-Nyhan patient. This substitution resulted in a nonsense mutation, CGA (Arg) to TGA (stop), at codon 51....
