The c.659T>G (p.V220G) alteration is located in exon 6 (coding exon 6) of the EXOSC5 gene. This alteration results from a T to G substitution at nucleotide position 659, causing the valine (V) at amino acid position 220 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
