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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-110263964-G-A is Pathogenic according to our data. Variant chr11-110263964-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 13186.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr11-110263964-G-A is described in Lovd as [Pathogenic].
