The c.836G>A (p.S279N) alteration is located in exon 8 (coding exon 8) of the EXOSC7 gene. This alteration results from a G to A substitution at nucleotide position 836, causing the serine (S) at amino acid position 279 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
