The c.478G>A (p.D160N) alteration is located in exon 3 (coding exon 2) of the SYNDIG1L gene. This alteration results from a G to A substitution at nucleotide position 478, causing the aspartic acid (D) at amino acid position 160 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
