Genes affected

FOXL2 (HGNC:1092): (forkhead box L2) This gene encodes a forkhead transcription factor. The protein contains a fork-head DNA-binding domain and may play a role in ovarian development and function. Expansion of a polyalanine repeat region and other mutations in this gene are a cause of blepharophimosis syndrome and premature ovarian failure 3. [provided by RefSeq, Jul 2016]

FOXL2 Gene-Disease associations (from GenCC):

blepharophimosis, ptosis, and epicanthus inversus syndrome

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 31 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Trascript score misZ: -0.80149 (below the threshold of 3.09). GenCC associations: The gene is linked to blepharophimosis, ptosis, and epicanthus inversus syndrome, premature ovarian failure 3.

PP5

Variant 3-138945678-G-C is Pathogenic according to our data. Variant chr3-138945678-G-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 134454.Status of the report is criteria_provided_single_submitter, 1 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.029051244). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAd4 at 32 AD,Unknown gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
