601002.0001; 5-OXOPROLINURIA |
| Identified Mutation |
ARG164GLN; In a family in which 2 brothers exhibited 5-oxoprolinuria, metabolic acidosis, hemolytic anemia, and mental retardation, Shi et al. (1996) found compound heterozygosity for mutations in the GSS gene: a G-to-A transition at the end of exon 4 (position 491) of the cDNA, which may cause an RNA splicing error or a missense mutation (arg164-to-gln); and, in exon 1, a deletion of G corresponding to nucleotide 3 or 4 in the cDNA sequence (+1ATGGCC...), predicting a frameshift and/or abolition of the translational initiation site. These 2 changes were designated as 491G-A and 3(4)delG, respectively.
