The c.2699G>A (p.R900H) alteration is located in exon 13 (coding exon 12) of the WAPL gene. This alteration results from a G to A substitution at nucleotide position 2699, causing the arginine (R) at amino acid position 900 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
