Genes affected
TSHR (HGNC:12373): (thyroid stimulating hormone receptor) The protein encoded by this gene is a membrane protein and a major controller of thyroid cell metabolism. The encoded protein is a receptor for thyrothropin and thyrostimulin, and its activity is mediated by adenylate cyclase. Defects in this gene are a cause of several types of hyperthyroidism. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

Hypothyroidism due to TSH receptor mutations Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingBaylor GeneticsMar 08, 2023- -
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMar 18, 2024Variant summary: TSHR c.1270G>A (p.Val424Ile) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251494 control chromosomes. To our knowledge, no occurrence of c.1270G>A in individuals affected with Hypothyroidism Due To TSH Receptor Mutations has been reported. At least one publication reports experimental evidence evaluating an impact on protein function (Haas_2011). The most pronounced variant effect results in 30%-50% of basal cAMP production compared to wild-type. The following publication has been ascertained in the context of this evaluation (PMID: 20652618). ClinVar contains an entry for this variant (Variation ID: 135398). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
