The c.980C>G (p.P327R) alteration is located in exon 10 (coding exon 9) of the SNRNP70 gene. This alteration results from a C to G substitution at nucleotide position 980, causing the proline (P) at amino acid position 327 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
