The c.565G>A (p.V189M) alteration is located in exon 6 (coding exon 4) of the PRSS54 gene. This alteration results from a G to A substitution at nucleotide position 565, causing the valine (V) at amino acid position 189 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
