Lesch-Nyhan disease (LND) is an X-linked genetic disorder caused by mutations of the hypoxanthine guanine phosphoribosyltransferase (HPRT) purine biosynthesis gene and characterized by aberrant purine metabolism, deficient basal ganglia dopamine levels, dystonia, and severe neurobehavioral manifestations, including compulsive self-injurious behavior.

Although these 'evolutionary conserved' amino acids account for only 32% of the amino acids in the human hprt protein, they are involved in 76% of the missense mutations at the hprt locus in human T-lymphocytes, 67% in Lesch-Nyhan patients (with severe hprt-deficiency), but only 43% in gout patients (with partial hprt deficiency).

Sequencing analysis of the amplified DNA from three different patients with HPRT deficiency implied three unique molecular abnormalities: 1) one single-base substitution at codon 54 (from ATG to CTG) resulting in the replacement of methionine with leucine in an LN patient, 2) two single-base substitutions at codon 179 (from GTT to GGT) and at codon 180 (from GGA to AGA) resulting in the replacement of valine with glycine and glycine with arginine in a gouty patient, and 3) 51 nucleotide deletion between nucleotides 747 and 797 resulting in the formation of shorter sized HPRT mRNA and putative two amino-acid deleted HPRT protein in another gouty patient.
