Genes affected

EID3 (HGNC:32961): (EP300 interacting inhibitor of differentiation 3) Predicted to be involved in DNA repair. Located in nucleolus and nucleoplasm. Part of Smc5-Smc6 complex. [provided by Alliance of Genome Resources, Apr 2022]

EID3 links:

TXNRD1 (HGNC:12437): (thioredoxin reductase 1) The protein encoded by this gene belongs to the pyridine nucleotide-disulfide oxidoreductase family, and is a member of the thioredoxin (Trx) system. Three thioredoxin reductase (TrxR) isozymes are found in mammals. TrxRs are selenocysteine-containing flavoenzymes, which reduce thioredoxins, as well as other substrates, and play a key role in redox homoeostasis. This gene encodes an ubiquitously expressed, cytosolic form of TrxR, which functions as a homodimer containing FAD, and selenocysteine (Sec) at the active site. Sec is encoded by UGA codon that normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, the Sec insertion sequence (SECIS) element, which is necessary for the recognition of UGA as a Sec codon rather than as a stop signal. Alternative splicing, primarily at the 5' end, results in transcript variants encoding same or different isoforms, including a glutaredoxin-containing isoform that is predominantly expressed in testis.

The c.25G>C (p.A9P) alteration is located in exon 1 (coding exon 1) of the EID3 gene. This alteration results from a G to C substitution at nucleotide position 25, causing the alanine (A) at amino acid position 9 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
