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 15 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, 0.987
PP5
Variant 3-24127631-G-A is Pathogenic according to our data. Variant chr3-24127631-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 12558.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Variant summary: THRB c.1012C>T (p.Arg338Trp) 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 251472 control chromosomes (gnomAD). c.1012C>T has been reported in the literature in multiple individuals affected with Thyroid Hormone Resistance and was shown to segregate with disease within families (e.g. Weiss_1993, Alberobello_2011, Macchia_2014, Arsov_2019). These data indicate that the variant is very likely to be associated with disease. Experimental evidence demonstrated the variant affects protein function (Sasaki_1995, Ando_1996, Wan_2005). Two ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

In the published literature, the variant has been reported in individuals affected with selective pituitary resistance to thyroid hormone (PRTH) (PMIDs: 8514853 (1993), 8384535 (1993), 8889584 (1996), 8040303 (1994), 11518118 (2001), 16804041 (2006), 25040256 (2014), 26041374 (2015), and 30430796 (2018)). This variant is located within a hotspot in the hormone-binding domain of THRB and results in significant reduction of its T3-binding activity (PMIDs: 8674808 (1995), 8384535 (1993), 25040256 (2014), and 24174637 (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. -
