Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PAX9 gene is commonly pathogenic or not. These statistics are base on transcript: NM_001372076.1. 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 required for normal development of thymus, parathyroid glands, ultimobranchial bodies, teeth, skeletal elements of skull and larynx as well as distal limbs. {ECO:0000250, ECO:0000269|PubMed:12657635}.
• Disease: DISEASE: Tooth agenesis, selective, 3 (STHAG3) [MIM:604625]: A form of selective tooth agenesis, a common anomaly characterized by the congenital absence of one or more teeth. Selective tooth agenesis without associated systemic disorders has sometimes been divided into 2 types: oligodontia, defined as agenesis of 6 or more permanent teeth, and hypodontia, defined as agenesis of less than 6 teeth. The number in both cases does not include absence of third molars (wisdom teeth). {ECO:0000269|PubMed:12786960}. Note=The disease is caused by mutations affecting the gene represented in this entry.
