Genes affected

THRB (HGNC:11799): (thyroid hormone receptor beta) The protein encoded by this gene is a nuclear hormone receptor for triiodothyronine. It is one of the several receptors for thyroid hormone, and has been shown to mediate the biological activities of thyroid hormone. Knockout studies in mice suggest that the different receptors, while having certain extent of redundancy, may mediate different functions of thyroid hormone. Mutations in this gene are known to be a cause of generalized thyroid hormone resistance (GTHR), a syndrome characterized by goiter and high levels of circulating thyroid hormone (T3-T4), with normal or slightly elevated thyroid stimulating hormone (TSH). Several alternatively spliced transcript variants encoding the same protein have been observed for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 13 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the THRB gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 58 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 2.5652 (below the threshold of 3.09). Trascript score misZ: 3.708 (above the threshold of 3.09). GenCC associations: The gene is linked to thyroid hormone resistance, generalized, autosomal dominant, resistance to thyroid hormone due to a mutation in thyroid hormone receptor beta, thyroid hormone resistance, generalized, autosomal recessive.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.913

PP5

Variant 3-24143511-C-T is Pathogenic according to our data. Variant chr3-24143511-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 12566.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Variant summary: THRB c.728G>A (p.Arg243Gln) results in a conservative amino acid change located in the Nuclear hormone receptor, ligand-binding domain (IPR000536) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 250376 control chromosomes. c.728G>A has been reported in the literature in multiple individuals affected with Generalized Autosomal Dominant Thyroid Hormone Resistance, (example, Chaves_2021). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function (example, Yagi_1997). The most pronounced variant effect results in 16% of normal T3-dependent transactivation activity. This suggests that the receptor DNA-binding domain can modulate the function of the hormone-binding domain via allosteric mechanisms. 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. -

The THRB c.728G>A variant is predicted to result in the amino acid substitution p.Arg243Gln. This variant has been reported in heterozygous patients with resistance to thyroid hormone (see, for example, Yagi et al. 1997. PubMed ID: 9141558; Lado Abeal et al. 2011. PubMed ID: 21703645; 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. -
