The c.2773G>A (p.D925N) alteration is located in exon 20 (coding exon 20) of the KIAA1324L gene. This alteration results from a G to A substitution at nucleotide position 2773, causing the aspartic acid (D) at amino acid position 925 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
