The c.767G>A (p.G256D) alteration is located in exon 5 (coding exon 5) of the YDJC gene. This alteration results from a G to A substitution at nucleotide position 767, causing the glycine (G) at amino acid position 256 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
