The c.694G>T (p.G232W) alteration is located in exon 6 (coding exon 6) of the PRSS33 gene. This alteration results from a G to T substitution at nucleotide position 694, causing the glycine (G) at amino acid position 232 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
