Collection Method: clinical testing

The c.22G>A (p.V8M) alteration is located in exon 2 (coding exon 1) of the FAM168A gene. This alteration results from a G to A substitution at nucleotide position 22, causing the valine (V) at amino acid position 8 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
