Genes affected

XRN1 (HGNC:30654): (5'-3' exoribonuclease 1) This gene encodes a member of the 5'-3' exonuclease family. The encoded protein may be involved in replication-dependent histone mRNA degradation, and interacts directly with the enhancer of mRNA-decapping protein 4. In addition to mRNA metabolism, a similar protein in yeast has been implicated in a variety of nuclear and cytoplasmic functions, including homologous recombination, meiosis, telomere maintenance, and microtubule assembly. Mutations in this gene are associated with osteosarcoma, suggesting that the encoded protein may also play a role in bone formation. Alternative splicing results in multiple transcript variants.

The c.4070G>A (p.R1357Q) alteration is located in exon 36 (coding exon 36) of the XRN1 gene. This alteration results from a G to A substitution at nucleotide position 4070, causing the arginine (R) at amino acid position 1357 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
