Genes affected

RFX2 (HGNC:9983): (regulatory factor X2) This gene is a member of the regulatory factor X gene family, which encodes transcription factors that contain a highly-conserved winged helix DNA binding domain. The protein encoded by this gene is structurally related to regulatory factors X1, X3, X4, and X5. It is a transcriptional activator that can bind DNA as a monomer or as a heterodimer with other RFX family members. This protein can bind to cis elements in the promoter of the IL-5 receptor alpha gene. Two transcript variants encoding different isoforms have been described for this gene, and both variants utilize alternative polyadenylation sites. [provided by RefSeq, Jul 2008]

The c.1394C>T (p.P465L) alteration is located in exon 12 (coding exon 11) of the RFX2 gene. This alteration results from a C to T substitution at nucleotide position 1394, causing the proline (P) at amino acid position 465 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
