The c.1457G>A (p.R486Q) alteration is located in exon 12 (coding exon 10) of the FAM126B gene. This alteration results from a G to A substitution at nucleotide position 1457, causing the arginine (R) at amino acid position 486 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
