The c.790G>T (p.A264S) alteration is located in exon 3 (coding exon 1) of the PRSS35 gene. This alteration results from a G to T substitution at nucleotide position 790, causing the alanine (A) at amino acid position 264 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
