The c.772C>G (p.P258A) alteration is located in exon 6 (coding exon 5) of the NOL4L gene. This alteration results from a C to G substitution at nucleotide position 772, causing the proline (P) at amino acid position 258 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
