The c.2360G>A (p.S787N) alteration is located in exon 18 (coding exon 18) of the FAM13A gene. This alteration results from a G to A substitution at nucleotide position 2360, causing the serine (S) at amino acid position 787 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
