The c.856G>A (p.D286N) alteration is located in exon 7 (coding exon 7) of the FAM131B gene. This alteration results from a G to A substitution at nucleotide position 856, causing the aspartic acid (D) at amino acid position 286 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
