The c.2341G>A (p.A781T) alteration is located in exon 15 (coding exon 15) of the CWF19L2 gene. This alteration results from a G to A substitution at nucleotide position 2341, causing the alanine (A) at amino acid position 781 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
