Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM1PM2PM5PP2PP3

The NM_000369.5(TSHR):​c.484C>A​(p.Pro162Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,613,870 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P162S) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 2 uncertain in NM_000369.5
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr14-81092547-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 623326.
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.797
