Collection Method: clinical testing

The c.206G>T (p.G69V) alteration is located in exon 2 (coding exon 1) of the FAM198B gene. This alteration results from a G to T substitution at nucleotide position 206, causing the glycine (G) at amino acid position 69 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
