The c.436G>A (p.G146S) alteration is located in exon 5 (coding exon 4) of the MUM1 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the glycine (G) at amino acid position 146 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
