Identification of a novel heterozygous TSC2 splicing variant in a patient with Tuberous sclerosis complex: A case report.

We identified a novel heterozygous TSC2 variant, c.336_336 + 15delGGTAAGGCCCAGGGCG, in a patient with classical TSC and demonstrated that this variant leads to aberrant splicing using a minigene assay. Our results extend the understanding of the mutational spectrum of TSC2.
