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.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 412 of the TH protein (p.Gln412Lys). This variant is present in population databases (rs121917762, gnomAD 0.0009%). This missense change has been observed in individuals with dopa-responsive dystonia (PMID: 7814018). It has also been observed to segregate with disease in related individuals. This variant is also known as Gln381Lys. ClinVar contains an entry for this variant (Variation ID: 12324). 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. Experimental studies have shown that this missense change affects TH function (PMID: 8528210, 8817341, 24753243, 26220941). For these reasons, this variant has been classified as Pathogenic.
