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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RFX3. . Gene score misZ 3.4728 (greater than the threshold 3.09). Trascript score misZ 3.1742 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder, autism spectrum disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.3173746).

The c.1653A>T (p.R551S) alteration is located in exon 15 (coding exon 13) of the RFX3 gene. This alteration results from a A to T substitution at nucleotide position 1653, causing the arginine (R) at amino acid position 551 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
