Genes affected

RFX3 (HGNC:9984): (regulatory factor X3) 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, X4, and X5. It is a transcriptional activator that can bind DNA as a monomer or as a heterodimer with other RFX family members. Multiple transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2013]

The RFX3 c.1672A>G variant is predicted to result in the amino acid substitution p.Met558Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-3257133-T-C). Of note, this variant is predicted to strongly active a cryptic donor site within exon 1 based on available splicing prediction programs (Alamut Visual v2.11). However, such computer prediction programs are imperfect. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
