The c.889G>A (p.A297T) alteration is located in exon 4 (coding exon 4) of the NOP9 gene. This alteration results from a G to A substitution at nucleotide position 889, causing the alanine (A) at amino acid position 297 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
