Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM2PM5PP2

The NM_000145.4(FSHR):​c.383C>T​(p.Ser128Phe) variant causes a missense change. The variant allele was found at a frequency of 0.00000138 in 1,452,200 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. S128Y) 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

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr2-48990629-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 16254.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.
