Genes affected

EXOSC4 (HGNC:18189): (exosome component 4) Enables mRNA 3'-UTR AU-rich region binding activity. Involved in nucleic acid metabolic process and positive regulation of cell growth. Acts upstream of or within defense response to virus. Located in cytosol; nucleoplasm; and transcriptionally active chromatin. Part of exosome (RNase complex).

The c.607G>A (p.A203T) alteration is located in exon 3 (coding exon 3) of the EXOSC4 gene. This alteration results from a G to A substitution at nucleotide position 607, causing the alanine (A) at amino acid position 203 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
