The c.682G>A (p.D228N) alteration is located in exon 11 (coding exon 8) of the FAM208B gene. This alteration results from a G to A substitution at nucleotide position 682, causing the aspartic acid (D) at amino acid position 228 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
