The c.2711G>A (p.G904E) alteration is located in exon 2 (coding exon 2) of the VCPIP1 gene. This alteration results from a G to A substitution at nucleotide position 2711, causing the glycine (G) at amino acid position 904 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
