The c.167A>G (p.N56S) alteration is located in exon 3 (coding exon 1) of the FAM103A1 gene. This alteration results from a A to G substitution at nucleotide position 167, causing the asparagine (N) at amino acid position 56 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
