Analysis of AGR1 gene variants in an infant with early-onset argininemia / 中华医学遗传学杂志

ABSTRACT

OBJECTIVE@#To explore the genetic basis for an infant with early-onset argininemia.@*METHODS@#Potential variant was detected with an Ion Torrent semiconductor sequencer using a gene panel for inherited diseases. Suspected variants were verified by Sanger sequencing.@*RESULTS@#Genetic testing indicated that he has carried c.560+2T>C and c.811T>C compound heterozygous variant of the AGR1 gene, which were inherited from his father and mother, respectively. Among these, c.560+2T>C was suspected to be pathogenic, while c.811T>C was of unknown clinical significance, and both were not reported previously.@*CONCLUSION@#The c.560+2T>C and c.811T>C compound heterozygous variants of the AGR1 gene probably underlies the argininemia in this child. Above finding has enriched the variant spectrum of the AGR1 gene.
