HUSP Clinical Genetics Laboratory, Hospital Universitario San Pedro De Logroño (HUSP) RCV004557270 SCV005046450 likely pathogenic Tuberous sclerosis 2 criteria provided, single submitter clinical testing The variant was detected in amniotic fluid of a fetus with cardiac rhabdomyoma. The fetus presented the variant c.5095delG in exon 40 of TSC2 in heterozygosity (NM_000548). It results in a delay of the termination codon of translation (p.Val1699TrpfsTer127). This variant is not detected in general population and has not been reported in pathogenic data bases. Pathogenic variants in TSC2 have been associated with Tuberous sclerosis (OMIM: 613254). This clinical entity is a multisystem disorder characterized by hamartomas in multiple organ systems, including the brain, skin, heart, kidneys, and lung. These changes can result in epilepsy, learning difficulties, behavioral problems, and renal failure, among other complications. For this reason, the parents decided to do a termination of pregnancy. This entity has autosomal dominant inheritance.
