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
    Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), G2P
  • premature ovarian failure 3

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 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.
BP4
Computational evidence support a benign effect (MetaRNN=0.0034596026).
BP6
Variant 3-138946187-G-C is Benign according to our data. Variant chr3-138946187-G-C is described in ClinVar as Benign. ClinVar VariationId is 261662.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BA1
GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.354 is higher than 0.05.
