The c.1256G>A (p.R419Q) alteration is located in exon 8 (coding exon 8) of the FAM117A gene. This alteration results from a G to A substitution at nucleotide position 1256, causing the arginine (R) at amino acid position 419 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
