Ambry Genetics

Apr 05, 2023

The c.274G>A (p.V92I) alteration is located in exon 4 (coding exon 3) of the TBCEL gene. This alteration results from a G to A substitution at nucleotide position 274, causing the valine (V) at amino acid position 92 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
