Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the FOXL2 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Transcriptional regulator. Critical factor essential for ovary differentiation and maintenance, and repression of the genetic program for somatic testis determination. Prevents trans- differentiation of ovary to testis through transcriptional repression of the Sertoli cell-promoting gene SOX9 (By similarity). Has apoptotic activity in ovarian cells. Suppresses ESR1-mediated transcription of PTGS2/COX2 stimulated by tamoxifen (By similarity). Is a regulator of CYP19 expression (By similarity). Participates in SMAD3-dependent transcription of FST via the intronic SMAD-binding element (By similarity). Is a transcriptional repressor of STAR. Activates SIRT1 transcription under cellular stress conditions. Activates transcription of OSR2. {ECO:0000250, ECO:0000269|PubMed:16153597, ECO:0000269|PubMed:19010791, ECO:0000269|PubMed:19429596, ECO:0000269|PubMed:19744555}.;
Disease
DISEASE: Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) [MIM:110100]: A disorder characterized by eyelid dysplasia, small palpebral fissures, drooping eyelids and a skin fold curving in the mediolateral direction, inferior to the inner canthus. In type I BPSE (BPES1) eyelid abnormalities are associated with female infertility. Affected females show an ovarian deficit due to primary amenorrhea or to premature ovarian failure (POF). In type II BPSE (BPES2) affected individuals show only the eyelid defects. {ECO:0000269|PubMed:11175783, ECO:0000269|PubMed:11468277, ECO:0000269|PubMed:12400065, ECO:0000269|PubMed:12529855, ECO:0000269|PubMed:12630957, ECO:0000269|PubMed:12938087, ECO:0000269|PubMed:15257268, ECO:0000269|PubMed:16454982, ECO:0000269|PubMed:17089161, ECO:0000269|PubMed:18372316, ECO:0000269|PubMed:18484667, ECO:0000269|PubMed:18642388, ECO:0000269|Ref.2}. Note=The disease is caused by mutations affecting the gene represented in this entry. There is a mutational hotspot in the region coding for the poly-Ala domain, since 30% of all mutations in the ORF lead to poly-Ala expansions, resulting mainly in BPES type II.; DISEASE: Premature ovarian failure 3 (POF3) [MIM:608996]: An ovarian disorder defined as the cessation of ovarian function under the age of 40 years. It is characterized by oligomenorrhea or amenorrhea, in the presence of elevated levels of serum gonadotropins and low estradiol. {ECO:0000269|PubMed:12149404, ECO:0000269|PubMed:19429596}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
