Fetal ultrasound and MRI imaging techniques have evolved and may capture even earlier the following TSC-associated lesions: cardiac rhabdomyomas, subependymal nodules, cortical tubers and renal cysts.
Typically rhabdomyomas are multiple lesions and usually regress spontaneously but are often associated with tuberous sclerosis complex (TSC), an autosomal dominant multisystem disorder caused by mutations in either of the two genes, TSC1 or TSC2.
Our aim for this study was to characterize the incidence, progression, and clinical consequences of tuberous sclerosis complex-associated rhabdomyomas in a large cohort of patients with TSC1 and TSC2 genotypes.
Familial molecular analysis of TSC1 and TSC2 in cases with prenatally diagnosed cardiac rhabdomyomas and cerebral tuberous sclerosis lesions is helpful in prenatal diagnosis and genetic counseling.
