The c.787G>T (p.A263S) alteration is located in exon 3 (coding exon 2) of the MUC22 gene. This alteration results from a G to T substitution at nucleotide position 787, causing the alanine (A) at amino acid position 263 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
