Ambry Genetics

Jul 09, 2024

The c.490G>T (p.V164F) alteration is located in exon 2 (coding exon 2) of the FAM83F gene. This alteration results from a G to T substitution at nucleotide position 490, causing the valine (V) at amino acid position 164 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
