The c.1919A>G (p.N640S) alteration is located in exon 22 (coding exon 22) of the DPY19L1 gene. This alteration results from a A to G substitution at nucleotide position 1919, causing the asparagine (N) at amino acid position 640 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
