The c.265C>T (p.P89S) alteration is located in exon 3 (coding exon 2) of the MON1B gene. This alteration results from a C to T substitution at nucleotide position 265, causing the proline (P) at amino acid position 89 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
