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]

CEP128 (HGNC:20359): (centrosomal protein 128) Involved in protein localization. Located in centriole and spindle pole. Part of centriolar subdistal appendage. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 43 curated pathogenic missense variants (we use a threshold of 10). 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 athyreosis, hypothyroidism due to TSH receptor mutations, familial hyperthyroidism due to mutations in TSH receptor, familial gestational hyperthyroidism, thyroid hypoplasia.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.776
