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 Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.25128904).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000274 (4/1461620) while in subpopulation EAS AF= 0.000101 (4/39688). AF 95% confidence interval is 0.0000335. There are 0 homozygotes in gnomad4_exome. There are 3 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.2204C>G (p.T735S) alteration is located in exon 18 (coding exon 16) of the RFX3 gene. This alteration results from a C to G substitution at nucleotide position 2204, causing the threonine (T) at amino acid position 735 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
