Genes affected

RFX4 (HGNC:9985): (regulatory factor X4) 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, X2, X3, and X5. It has been shown to interact with itself as well as with regulatory factors X2 and X3, but it does not interact with regulatory factor X1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2011]

The c.991C>T (p.R331W) alteration is located in exon 10 (coding exon 10) of the RFX4 gene. This alteration results from a C to T substitution at nucleotide position 991, causing the arginine (R) at amino acid position 331 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
