Ambry Genetics

Aug 23, 2021

The c.598G>A (p.V200M) alteration is located in exon 5 (coding exon 5) of the TBC1D9B gene. This alteration results from a G to A substitution at nucleotide position 598, causing the valine (V) at amino acid position 200 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
