Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RFX5 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: Activates transcription from class II MHC promoters. Recognizes X-boxes. Mediates cooperative binding between RFX and NF-Y. RFX binds the X1 box of MHC-II promoters.
• Disease: DISEASE: Bare lymphocyte syndrome 2 (BLS2) [MIM:209920]: A severe combined immunodeficiency disease with early onset. It is characterized by a profound defect in constitutive and interferon- gamma induced MHC II expression, absence of cellular and humoral T-cell response to antigen challenge, hypogammaglobulinemia and impaired antibody production. The consequence include extreme susceptibility to viral, bacterial and fungal infections. {ECO:0000269|PubMed:10825209}. Note=The disease is caused by mutations affecting the gene represented in this entry.
