Variant summary
Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PM2PM5PP2PP3_StrongPP5_Very_Strong
The NM_001354712.2(THRB):c.1357C>T(p.Pro453Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P453L) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | Oct 17, 2022 | The frequency of this variant in the general population, 0.000032 (1/31396 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in individuals and families affected with resistance to thyroid hormone (RTH) (PMIDs: 8040303 (1994), 26041374 (2015), 27743306 (2017), and 30430796 (2018)). Functional studies suggest the variant is damaging to proper protein function (PMID: 21622532 (2011)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, this variant is classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Oct 02, 2023 | Published functional studies demonstrate a damaging effect with a significantly reduced binding affinity (Adams et al., 1994); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 27743306, 8040303, 26041374, 21622532, 7833659, 30430796) - |

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 05, 2023 | Variant summary: THRB c.1357C>T (p.Pro453Ser) results in a non-conservative amino acid change located in the Nuclear hormone receptor, ligand-binding domain (IPR000536) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251490 control chromosomes (gnomAD). c.1357C>T has been reported in the literature in multiple individuals affected with Resistance to thyroid hormone/Reduced sensitivity to thyroid hormone/generalized growth disorder (example: Refetoff_1994, Adams_1994, Han_2015, and Kannan_2017) and at least one individual was reported as a de novo occurrence (Zaig_2018). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence that the variant impairs normal protein function (example: Lee_2011). One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
