Variant summary
Our verdict is Pathogenic. The variant received 15 ACMG points: 15P and 0B. PM2PP2PP3_StrongPP5_Very_Strong
The NM_001354712.2(THRB):c.1286G>A(p.Arg429Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,132 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. R429W) has been classified as Uncertain significance.

Thyroid hormone resistance, generalized, autosomal dominant Pathogenic:2
Variant summary: THRB c.1286G>A (p.Arg429Gln) results in a conservative amino acid change located in the Nuclear hormone receptor, ligand-binding domain (IPR000536) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251492 control chromosomes. c.1286G>A has been reported in the literature in multiple individuals affected with autosomal dominant generalized and pitutary Thyroid Hormone Resistance (example, Flynn_1994, Adams_1994, Taniyama_2001, Kong_2005, Abeal_2011, Dieu_2020). These data indicate that the variant is very likely to be associated with disease. Multiple publications report experimental evidence evaluating an impact on protein function (example, Flynn_1994, Adams_1994, Wei Wan_2005). The most pronounced variant effect results in approximately 20% of normal affinity for T3 hormone binding by the mutant receptors (Adams_1994). One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
not provided Pathogenic:1
The frequency of this variant in the general population, 0.0000066 (1/152132 chromosomes, http://gnomad.broadinstitute.org), is consistent with pathogenicity. In the published literature, the variant has been reported in individuals with resistance to thyroid hormone (RTH) (PMIDs: 8040303 (1994), 7528740 (1994), 11167935 (2001), 21703645 (2011), and 32635414 (2020)). Functional studies show damaging effects on homodimerization, protein-protein binding and gene repression (PMIDs: 7528740 (1994), 8040303 (1994), 10847591 (2000), 19439650 (2009), 21622532 (2011), and 25040256 (2014)). 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.
THRB-related disorder Pathogenic:1
The THRB c.1286G>A variant is predicted to result in the amino acid substitution p.Arg429Gln. This variant has been reported in multiple patients with thyroid hormone resistance (Adams et al. 1994. PubMed ID: 8040303; Macchia et al. 2014. PubMed ID: 25040256). This variant has not been reported in a large population database, indicating this variant is rare. This variant is interpreted as pathogenic.
