Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PS1_Moderate PM2 PM5 PP3_Moderate PP5

The NM_000369.5(TSHR):c.842G>A(p.Ser281Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S281I) has been classified as 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

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PS1: Transcript NM_000369.5 (TSHR) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr14-81139828-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 6446.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.867
• PP5: Variant 14-81139828-G-A is Pathogenic according to our data. Variant chr14-81139828-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 6452.Status of the report is no_assertion_criteria_provided, 0 stars.
