The c.1000C>T (p.R334W) alteration is located in exon 5 (coding exon 5) of the CEACAM20 gene. This alteration results from a C to T substitution at nucleotide position 1000, causing the arginine (R) at amino acid position 334 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
