Abstract
A syndrome of hyperuricemia, sensorineural deafness, mild mental handicap and congenital disequilibrium in a four-year-old boy is probably inherited as a sex-linked condition since his mother has sensorineural deafness and similar biochemical abnormalities. There is evidence of a superactive PP-ribose-P synthetase, normal purine salvage enzymes, and severe depletion of nicotinamide adenine dinucleotide and guanine triphosphate in red cells.
