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]

The gene has 11 curated benign missense variants. Gene score misZ: 0.33445 (below the threshold of 3.09). Trascript score misZ: 1.3127 (below the threshold of 3.09). GenCC associations: The gene is linked to hypothyroidism due to TSH receptor mutations, athyreosis, familial hyperthyroidism due to mutations in TSH receptor, familial gestational hyperthyroidism, thyroid hypoplasia.
BP4
Computational evidence support a benign effect (MetaRNN=0.0018980801).
BP6
Variant 14-81144290-C-G is Benign according to our data. Variant chr14-81144290-C-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 135396.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Hypothyroidism due to TSH receptor mutations Benign:1
Jan 13, 2018
Illumina Laboratory Services, Illumina
Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
