Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP2 PP3

The NM_001354712.2(THRB):​c.1251T>G​(p.Phe417Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. F417F) has been classified as Benign.

Genes affected

THRB (HGNC:11799): (thyroid hormone receptor beta) 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. Mutations in this gene are known to be a cause of generalized thyroid hormone resistance (GTHR), a syndrome characterized by goiter and high levels of circulating thyroid hormone (T3-T4), with normal or slightly elevated thyroid stimulating hormone (TSH). Several alternatively spliced transcript variants encoding the same protein have been observed for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the THRB gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 58 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 2.5652 (below the threshold of 3.09). Trascript score misZ: 3.708 (above the threshold of 3.09). GenCC associations: The gene is linked to thyroid hormone resistance, generalized, autosomal dominant, resistance to thyroid hormone due to a mutation in thyroid hormone receptor beta, thyroid hormone resistance, generalized, autosomal recessive.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.745
