Comment:

The THRB c.1030G>A variant is predicted to result in the amino acid substitution p.Gly344Arg. This variant has been reported in the heterozygous state in individuals with resistance to thyroid hormone (Cunha et al. 2019. PubMed ID: 31326901; https://austinpublishinggroup.com/pediatric-endocrinology/fulltext/jpe-v8-id1056.php).
