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.

This sequence change creates a premature translational stop signal (p.Arg129*) 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). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with tyrosine hydroxylase deficiency (PMID: 27934587). ClinVar contains an entry for this variant (Variation ID: 374732). For these reasons, this variant has been classified as Pathogenic. -
