"[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.].
