The c.1865G>T (p.R622I) alteration is located in exon 21 (coding exon 21) of the DPY19L1 gene. This alteration results from a G to T substitution at nucleotide position 1865, causing the arginine (R) at amino acid position 622 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
