The c.1276G>A (p.D426N) alteration is located in exon 11 (coding exon 11) of the FAM13C gene. This alteration results from a G to A substitution at nucleotide position 1276, causing the aspartic acid (D) at amino acid position 426 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
