The c.878G>A (p.G293E) alteration is located in exon 7 (coding exon 6) of the CLIP4 gene. This alteration results from a G to A substitution at nucleotide position 878, causing the glycine (G) at amino acid position 293 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
