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.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.05515004 fraction of the gene. Cryptic splice site detected, with MaxEntScore 8, offset of 6, new splice context is: ttgcctccatccaatgccAGgtc. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

BP6

Variant 17-40076870-G-A is Benign according to our data. Variant chr17-40076870-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 561132.

BS2

High AC in GnomAd4 at 10 AD gene.
