Variant analysis of a patient with dyshormonogenesis due to congenital hypothyroidism / 中华医学遗传学杂志

ABSTRACT

OBJECTIVE@#To carry out variant analysis for a Chinese boy featuring dyshormonogenesis due to congenital hypothyroidism.@*METHODS@#DNA of the patient and his parents was extracted and sequenced by high-throughput sequencing. The results were validated with Sanger sequencing and analyzed with Bioinformatics software.@*RESULTS@#Sequencing result showed that the patient has carried compound variants of c.2654G>T(p.Arg885Leu) and c.943G>T(p.Gly315X) of the DUOX2 gene, which were inherited respectively from his mother and father.@*CONCLUSION@#The missense mutation c.2654G>T and nonsense mutation c.943G>T probably underlie the disease in this child.
