The c.498C>G (p.S166R) alteration is located in exon 1 (coding exon 1) of the FAM120AOS gene. This alteration results from a C to G substitution at nucleotide position 498, causing the serine (S) at amino acid position 166 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
