Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PP3_Strong

The NM_000369.5(TSHR):​c.561T>A​(p.Asn187Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. N187N) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: TSHR NM_000369.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.734

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]

(HGNC:):

ACMG classification
