The c.2303A>G (p.Y768C) alteration is located in exon 15 (coding exon 15) of the CWF19L2 gene. This alteration results from a A to G substitution at nucleotide position 2303, causing the tyrosine (Y) at amino acid position 768 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
