The c.447C>G (p.S149R) alteration is located in exon 3 (coding exon 3) of the CEACAM20 gene. This alteration results from a C to G substitution at nucleotide position 447, causing the serine (S) at amino acid position 149 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
