Collection Method: clinical testing

The c.613A>G (p.I205V) alteration is located in exon 2 (coding exon 1) of the FAM198B gene. This alteration results from a A to G substitution at nucleotide position 613, causing the isoleucine (I) at amino acid position 205 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
