Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the POF1B gene is commonly pathogenic or not. These statistics are base on transcript: NM_000024921.4. Only rare variants are included in the table.

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: Plays a key role in the organization of epithelial monolayers by regulating the actin cytoskeleton. May be involved in ovary development. {ECO:0000269|PubMed:16773570, ECO:0000269|PubMed:21940798}.
• Disease: DISEASE: Premature ovarian failure 2B (POF2B) [MIM:300604]: 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:16773570, ECO:0000269|PubMed:21940798}. Note=The disease is caused by mutations affecting the gene represented in this entry.
