Genes affected
ZC3H12C (HGNC:29362): (zinc finger CCCH-type containing 12C) Predicted to enable endoribonuclease activity and mRNA binding activity. Predicted to be involved in RNA phosphodiester bond hydrolysis, endonucleolytic. Predicted to be active in cytoplasmic ribonucleoprotein granule and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
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]

The c.340A>G (p.T114A) alteration is located in exon 2 (coding exon 2) of the ZC3H12C gene. This alteration results from a A to G substitution at nucleotide position 340, causing the threonine (T) at amino acid position 114 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
