The c.2621A>G (p.K874R) alteration is located in exon 18 (coding exon 18) of the CWF19L2 gene. This alteration results from a A to G substitution at nucleotide position 2621, causing the lysine (K) at amino acid position 874 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
