The c.527C>T (p.T176M) alteration is located in exon 2 (coding exon 2) of the NOP9 gene. This alteration results from a C to T substitution at nucleotide position 527, causing the threonine (T) at amino acid position 176 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
