The c.1417C>G (p.R473G) alteration is located in exon 7 (coding exon 7) of the A1BG gene. This alteration results from a C to G substitution at nucleotide position 1417, causing the arginine (R) at amino acid position 473 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
