The c.292G>C (p.A98P) alteration is located in exon 2 (coding exon 1) of the NAA30 gene. This alteration results from a G to C substitution at nucleotide position 292, causing the alanine (A) at amino acid position 98 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
