Tuberous sclerosis complex (TSC) is a neurocutaneous autosomal dominant disorder that results from mutations within either the TSC1 gene or the TSC2 gene. Diagnosis is based on well-established clinical criteria or genetic criteria. Clinical features are highly variable and could be developing over the life. We present a case of TSC with a molecular test that identified a novel variant in TSC2 gene. It is a sporadic missense mutation which has not been previously reported in the literature. It is caused by premature termination of protein translation and results in the production of truncated and non-functional proteins. This mutation is considered as a pathogenic variant and allows to broaden the spectrum of variants of TSC2 gene as a cause of TSC.

Keywords : Tuberous sclerosis 2; Phenotype; Genotype-phenotype correlation.
