The c.1489G>A (p.D497N) alteration is located in exon 12 (coding exon 10) of the SAMD3 gene. This alteration results from a G to A substitution at nucleotide position 1489, causing the aspartic acid (D) at amino acid position 497 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
