Ambry Genetics

Apr 12, 2022

The c.478A>G (p.I160V) alteration is located in exon 4 (coding exon 4) of the TEX40 gene. This alteration results from a A to G substitution at nucleotide position 478, causing the isoleucine (I) at amino acid position 160 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
