Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the POU3F3 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000006236.3. 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: Transcription factor that acts synergistically with SOX11 and SOX4. Plays a role in neuronal development. Is implicated in an enhancer activity at the embryonic met- mesencephalic junction; the enhancer element contains the octamer motif (5'-ATTTGCAT-3') (By similarity). {ECO:0000250}.
