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]

  • congenital nongoitrous hypothyroidism 6

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PM1
In a domain NR LBD (size 244) in uniprot entity THA_HUMAN there are 13 pathogenic changes around while only 1 benign (93%) in NM_199334.5
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.
BP4
Computational evidence support a benign effect (MetaRNN=0.003766179).
BP6
Variant 17-40084747-A-G is Benign according to our data. Variant chr17-40084747-A-G is described in ClinVar as [Benign]. Clinvar id is 738227.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAd4 at 47 AD gene.
