The c.1858G>A (p.E620K) alteration is located in exon 14 (coding exon 14) of the CFAP46 gene. This alteration results from a G to A substitution at nucleotide position 1858, causing the glutamic acid (E) at amino acid position 620 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
