The c.2416G>A (p.V806M) alteration is located in exon 19 (coding exon 19) of the FAM13A gene. This alteration results from a G to A substitution at nucleotide position 2416, causing the valine (V) at amino acid position 806 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
