The c.521A>G (p.K174R) alteration is located in exon 3 (coding exon 3) of the CFAP157 gene. This alteration results from a A to G substitution at nucleotide position 521, causing the lysine (K) at amino acid position 174 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
