Involvement in diseasei

Hyperoxaluria primary 1 (HP1)22 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn inborn error of glyoxylate metabolism characterized by increased excretion of oxalate and glycolate, and progressive tissue accumulation of insoluble calcium oxalate. Affected individuals are at risk for nephrolithiasis, nephrocalcinosis and early onset end-stage renal disease.

Polymorphismi

Polymorphism at position 11 acts synergistically with different mutations in AGXT producing specific enzymic phenotypes in HP1 patients. The combined presence of Leu-11 and Met-340 polymorphisms defines the minor AGXT allele, whereas their absence defines the major allele. The minor allele has frequencies of 20% in normal European and North American populations, and 50% in HP1 patients.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
