The c.1082G>A (p.R361Q) alteration is located in exon 8 (coding exon 7) of the ARFIP2 gene. This alteration results from a G to A substitution at nucleotide position 1082, causing the arginine (R) at amino acid position 361 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
