Collection Method: clinical testing

The c.457C>G (p.L153V) alteration is located in exon 7 (coding exon 7) of the FAM122C gene. This alteration results from a C to G substitution at nucleotide position 457, causing the leucine (L) at amino acid position 153 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
