Abstract:
The clinical data of one patient with autoimmune polyendocrinopathy syndrome type I were collected. PCR-DNA direct bidirectional sequencing was applied for mutation screening of 14 exons in autoimmune regulator (AIRE) gene in the patient and her parents. A total of 50 unrelated healthy controls were selected and tested. The bioinformatic methods were used to predict the possible impact of the mutations on the structure and function of the AIRE protein. The results of sequencing showed that heterozygous mutation c.622G>T (p.G208W) in exon 5 of the AIRE gene was detected in the patient and was a novel mutation, which had not been reported in the HGMD database and latest articles. This mutation was not detected in the 50 unrelated normal controls. The novel mutation of c.622G>T (p.G208W) in AIRE gene might play an important role in the pathogenesis of this case of autoimmune polyendocrinopathy syndrome type I.
