The c.1462A>C (p.K488Q) alteration is located in exon 8 (coding exon 8) of the FAM171A2 gene. This alteration results from a A to C substitution at nucleotide position 1462, causing the lysine (K) at amino acid position 488 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
