The c.1639G>A (p.V547M) alteration is located in exon 16 (coding exon 16) of the GOLGA8B gene. This alteration results from a G to A substitution at nucleotide position 1639, causing the valine (V) at amino acid position 547 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
