Abstract:
OBJECTIVETo identify the mutation of the autoimmune regulator gene (AIRE) in a Chinese family with autoimmune polyendocrinopathy syndrome type I (APS-I).
METHODSThe AIRE gene mutations were detected using PCR and direct DNA sequencing. Restriction enzyme analysis was used to confirm the mutations and bioinformatic methods were used to predict the possible impact of the mutations on the structure and function of the AIRE protein.
RESULTSA compound heterozygous mutation of A19T/R257X was detected in the proband. Her father had the A19T mutation in exon 1, but this mutation was not detected in 100 unrelated healthy individuals. Her mother had the R257X mutation in exon 6.
CONCLUSIONThis is the first report about AIRE mutations in Chinese APS-I kindred. The A19T mutation identified in this study has not been reported in the human gene mutation database (HGMD); the R257X has not been reported in Asians.
