Feb 12, 2024

The c.859G>A (p.V287M) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a G to A substitution at nucleotide position 859, causing the valine (V) at amino acid position 287 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
