Genes affected

RDX (HGNC:9944): (radixin) Radixin is a cytoskeletal protein that may be important in linking actin to the plasma membrane. It is highly similar in sequence to both ezrin and moesin. The radixin gene has been localized by fluorescence in situ hybridization to 11q23. A truncated version representing a pseudogene (RDXP2) was assigned to Xp21.3. Another pseudogene that seemed to lack introns (RDXP1) was mapped to 11p by Southern and PCR analyses. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.835

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000781 (114/1458936) while in subpopulation SAS AF= 0.000801 (69/86154). AF 95% confidence interval is 0.000649. There are 2 homozygotes in gnomad4_exome. There are 66 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 86 of the RDX protein (p.Pro86Ala). This variant is present in population databases (rs376418131, gnomAD 0.07%). This missense change has been observed in individual(s) with non-syndromic deafness (PMID: 32860223). ClinVar contains an entry for this variant (Variation ID: 229198). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Pro86Ala variant in RDX has not been previously reported in individuals wi th hearing loss, but has been identified in 0.1% (13/16304) of South Asian chrom osomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org ; dbSNP rs376418131). Although this variant has been seen in the general populat ion, its frequency is not high enough to rule out a pathogenic role. Computation al prediction tools and conservation analysis suggest that the p.Pro86Ala varian t may impact the protein, though this information is not predictive enough to de termine pathogenicity. In summary, the clinical significance of the p.Pro86Ala v ariant is uncertain. -
