%X OBJECTIVE: To explore the genetic basis for a patient presenting with renal insufficiency.
METHODS: The patient was subjected to whole exome sequencing, and the candidate variant was verified by Sanger sequencing. Transcriptional activity of the PAX2 gene was analyzed by using a PRS4-EGFP reporter plasmid.
RESULTS: Genetic testing revealed that the patient has carried a novel de novo heterozygous variant c.418C>T (p.Arg140Trp) of the PAX2 gene. The influence of c.389C>G (p.Pro130Arg), c.478G>A (p.Ala160Thr), c.418C>G (p. Arg140Gly) and c.418C>T (p.Arg140Trp) variants on the transcriptional activity was also evaluated. Functional study has illustrated that the PAX2-P130R, PAX2-R140G and PAX2-R140W variants all had a significant inhibitory effect on the transcriptional activity, but not the PAX2-A160T variant.
CONCLUSIONS: The isolated renal hypoplasia of the proband is probably due to the likely pathogenic variant of the PAX2 gene.
