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, 0.964

PP5

Variant 3-24122957-C-T is Pathogenic according to our data. Variant chr3-24122957-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 12559.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Variant summary: THRB c.1313G>A (p.Arg438His) 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 251486 control chromosomes (gnomAD). c.1313G>A has been reported in the literature in multiple individuals affected with Thyroid Hormone Resistance, Generalized, Autosomal Dominant (examples: Adams_1994, Han_2015). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 26041374, 8040303). Two submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.003%). Predicted Consequence/Location: Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.92 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.94 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change(ClinVar ID: VCV000012559 /PMID: 1677564) and different missense changes at the same codon (p.Arg438Cys, p.Arg438Pro / ClinVar ID: VCV000492921 /PMID: 25738994, 8040303) have been previously reported as pathogenic/likely pathogenic with strong evidence. Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
