The c.625C>G (p.Q209E) alteration is located in exon 7 (coding exon 7) of the DPYSL4 gene. This alteration results from a C to G substitution at nucleotide position 625, causing the glutamine (Q) at amino acid position 209 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
