The c.1163A>G (p.E388G) alteration is located in exon 10 (coding exon 10) of the FAM13C gene. This alteration results from a A to G substitution at nucleotide position 1163, causing the glutamic acid (E) at amino acid position 388 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
