Genes affected

RFX1 (HGNC:9982): (regulatory factor X1) This gene encodes a member of the regulatory factor X (RFX) family of transcription factors, which are characterized by a winged-helix DNA-binding domain. The encoded transcription factor contains an N-terminal activation domain and a C-terminal repression domain, and may activate or repress target gene expression depending on cellular context. This transcription factor has been shown to regulate a wide variety of genes involved in immunity and cancer, including the MHC class II genes and genes that may be involved in cancer progression. This gene exhibits altered expression in glioblastoma and the autoimmune disease systemic lupus erythematosis (SLE). [provided by RefSeq, Jul 2016]

The c.2282C>T (p.A761V) alteration is located in exon 17 (coding exon 16) of the RFX1 gene. This alteration results from a C to T substitution at nucleotide position 2282, causing the alanine (A) at amino acid position 761 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
