Collection Method: clinical testing

The c.549A>G (p.I183M) alteration is located in exon 7 (coding exon 7) of the FAM122C gene. This alteration results from a A to G substitution at nucleotide position 549, causing the isoleucine (I) at amino acid position 183 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
