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]

Our verdict: Likely_pathogenic. The variant received 9 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 resistance to thyroid hormone due to a mutation in thyroid hormone receptor beta, thyroid hormone resistance, generalized, autosomal recessive, thyroid hormone resistance, generalized, autosomal dominant.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.991

PP5

Variant 3-24123122-C-T is Pathogenic according to our data. Variant chr3-24123122-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 12568.Status of the report is criteria_provided_single_submitter, 1 stars.
