The c.938C>T (p.A313V) alteration is located in exon 11 (coding exon 11) of the DPY19L1 gene. This alteration results from a C to T substitution at nucleotide position 938, causing the alanine (A) at amino acid position 313 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
