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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

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.
BS2
High AC in GnomAdExome4 at 9 AD gene.

The c.287G>T (p.C96F) alteration is located in exon 5 (coding exon 4) of the THRA gene. This alteration results from a G to T substitution at nucleotide position 287, causing the cysteine (C) at amino acid position 96 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
