The c.275G>C (p.S92T) alteration is located in exon 3 (coding exon 2) of the MON1B gene. This alteration results from a G to C substitution at nucleotide position 275, causing the serine (S) at amino acid position 92 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
