RCV000334617 | SCV000389152 | likely benign | Familial hyperthyroidism due to mutations in TSH receptor | 2018-01-13 | criteria provided, single submitter | 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. |

RCV000401092 | SCV000389153 | uncertain significance | Hypothyroidism due to TSH receptor mutations | 2018-01-13 | criteria provided, single submitter | 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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |

RCV003401322 | SCV004122171 | uncertain significance | not specified | 2023-10-26 | criteria provided, single submitter | clinical testing | Variant summary: TSHR c.2120G>A (p.Arg707Gln) 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 8.8e-05 in 251258 control chromosomes. To our knowledge, no occurrence of c.2120G>A in individuals affected with Hypothyroidism Due To TSH Receptor Mutations and no experimental evidence demonstrating its impact on protein function have been reported. One submitter has cited two conflicting clinical-significance assessments for this variant to ClinVar after 2014, classifying the variant as both uncertain significance and likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance. |
