Collection Method: clinical testing

The c.460G>A (p.V154M) alteration is located in exon 4 (coding exon 4) of the FAM151B gene. This alteration results from a G to A substitution at nucleotide position 460, causing the valine (V) at amino acid position 154 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
