Genes affected

THRA (HGNC:11796): (thyroid hormone receptor alpha) 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. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

THRA Gene-Disease associations (from GenCC):

• congenital nongoitrous hypothyroidism 6

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: PanelApp Australia, G2P, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the THRA gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 11 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 3.4693 (above the threshold of 3.09). Trascript score misZ: 4.6029 (above the threshold of 3.09). GenCC associations: The gene is linked to congenital nongoitrous hypothyroidism 6.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.971
• PP5: Variant 17-40089416-C-G is Pathogenic according to our data. Variant chr17-40089416-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 192273.Status of the report is no_assertion_criteria_provided, 0 stars.
