Comment when marking as ready: Included in this panel as TFTs potentially suggestive of hyperthyroidism – elevated T3, non-suppressed TSH, even though the associated condition is hypothyroidism.

Green List (high evidence)

The altered THRα is thought to act in a dominant-negative fashion and inhibit wild-type THRα.
ClinGen review: no evidence for haploinsufficiency.

The phenotype is variable, but consistent with manifestations of untreated congenital hypothyroidism in peripheral tissues. Clinical features may be mild.

The HPT axis in patients carrying pathogenic variants in THRA is minimally affected. Patients have circulating TSH levels within the normal range, slightly lowered levels of free T4 and slightly elevated levels of total T3, which results in an abnormally low free T4:T3 ratio.
