Labcorp Genetics (formerly Invitae), Labcorp	RCV000671827	SCV000947427	pathogenic	Autosomal recessive DOPA responsive dystonia	2024-11-07	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Arg153*) in the TH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TH are known to be pathogenic (PMID: 22264700, 24753243). This variant is present in population databases (rs771610752, gnomAD 0.06%). This premature translational stop signal has been observed in individuals with tyrosine hydroxylase deficiency (PMID: 20056467, 22264700, 28087438). ClinVar contains an entry for this variant (Variation ID: 449110). For these reasons, this variant has been classified as Pathogenic.
3billion, Medical Genetics	RCV000671827	SCV002058733	pathogenic	Autosomal recessive DOPA responsive dystonia	2022-01-03	criteria provided, single submitter	clinical testing	Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000059, PM2_M). The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000449110, PMID:20056467). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.
