Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000042810 SCV000967770 pathogenic Tuberous sclerosis syndrome 2018-04-20 criteria provided, single submitter clinical testing The p.Tyr1250X variant in TSC2 has been reported in 5 individuals with tuberous sclerosis complex (TSC; Dabora 2001, Tyburczy 2014, Cai 2017, Tuberous sclerosis LOVD database: http://chromium.lovd.nl/LOVD2/TSC) and was absent from large pop ulation studies. This nonsense variant leads to a premature termination codon at position 1250, which is predicted to lead to a truncated or absent protein. Het erozygous loss of function of the TSC2 gene is an established disease mechanism in individuals with TSC. In summary, this variant meets criteria to be classifie d as pathogenic for TSC in an autosomal dominant manner based upon presence in m ultiple affected individuals, absence from the general population and predicted impact to protein. ACMG/AMP Criteria applied: PVS1, PM2, PS4_Moderate.
