Genes affected
TH (HGNC:11782): (tyrosine hydroxylase) The protein encoded by this gene is involved in the conversion of tyrosine to dopamine. It is the rate-limiting enzyme in the synthesis of catecholamines, hence plays a key role in the physiology of adrenergic neurons. Mutations in this gene have been associated with autosomal recessive Segawa syndrome. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

Autosomal recessive DOPA responsive dystonia Uncertain:3
Uncertain significance, criteria provided, single submitterclinical testingCentre for Mendelian Genomics, University Medical Centre LjubljanaSep 28, 2018This variant was classified as: Uncertain significance. The available evidence on this variant's pathogenicity is insufficient or conflicting. The following ACMG criteria were applied in classifying this variant: PM2,PP3. -
Uncertain significance, no assertion criteria providedclinical testingNatera, Inc.Nov 11, 2019- -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 31, 2022This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 68 of the TH protein (p.Arg68His). This variant is present in population databases (rs368122376, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with TH-related conditions. ClinVar contains an entry for this variant (Variation ID: 455993). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TH protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
