The c.280G>A (p.E94K) alteration is located in exon 4 (coding exon 3) of the ARFIP2 gene. This alteration results from a G to A substitution at nucleotide position 280, causing the glutamic acid (E) at amino acid position 94 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
