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.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 12 uncertain in NM_000360.4
PP5
Variant 11-2164325-C-T is Pathogenic according to our data. Variant chr11-2164325-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 412030.
BP4
Computational evidence support a benign effect (MetaRNN=0.21288428). . Strength limited to SUPPORTING due to the PP5.
