Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. PP2 BP4_Moderate

The ENST00000298171.7(TSHR):​c.1033G>A​(p.Asp345Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000198 in 1,461,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as not provided (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D345Y) has been classified as Uncertain significance.

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]

TSHR Gene-Disease associations (from GenCC):

• familial gestational hyperthyroidism

ENSG00000284959 (HGNC:58172):

ACMG classification

Our verdict: Likely_benign. The variant received -1 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 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=0.15379307).
