The c.1166A>G (p.K389R) alteration is located in exon 2 (coding exon 1) of the AFTPH gene. This alteration results from a A to G substitution at nucleotide position 1166, causing the lysine (K) at amino acid position 389 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
