Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM2 PM5 PP2 PP3_Strong PP5

The NM_000145.4(FSHR):​c.1346C>T​(p.Thr449Ile) 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 variant affecting the same amino acid position, but resulting in a different missense (i.e. T449A) has been classified as Pathogenic.

Genes affected

FSHR (HGNC:3969): (follicle stimulating hormone receptor) The protein encoded by this gene belongs to family 1 of G-protein coupled receptors. It is the receptor for follicle stimulating hormone and functions in gonad development. Mutations in this gene cause ovarian dysgenesis type 1, and also ovarian hyperstimulation syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr2-48963476-T-C is described in ClinVar as Pathogenic. ClinVar VariationId is 16252.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 23 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: -0.79874 (below the threshold of 3.09). Trascript score misZ: -0.97417 (below the threshold of 3.09). GenCC associations: The gene is linked to ovarian hyperstimulation syndrome, ovarian dysgenesis 1, 46 XX gonadal dysgenesis.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.97
• PP5: Variant 2-48963475-G-A is Pathogenic according to our data. Variant chr2-48963475-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 16249.Status of the report is no_assertion_criteria_provided, 0 stars.
