ABSTRACT

OBJECTIVE@#To perform gene mutation analysis in a patient with atypical clinical manifestations of tuberous sclerosis (TSC) for definite diagnosis.@*METHODS@#Peripheral blood DNA was obtained from a patient with clinically suspected TSC and her parents, and all exons and their flanking sequences of @*RESULTS@#A heterozygous nonsense mutation c.1096G>T (p.E366*) was identified in the exon 11 of the @*CONCLUSIONS@#The somatic mosaic mutation c.1096G>T (p.e366*) may be responsible for the phenotype of TSC in this patient. And the drop digital PCR is expected to be a diagnostic method for somatic cells mosaicism.
