The c.533G>A (p.R178Q) alteration is located in exon 4 (coding exon 3) of the MON1B gene. This alteration results from a G to A substitution at nucleotide position 533, causing the arginine (R) at amino acid position 178 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
