May 17, 2023

The c.967G>T (p.V323L) alteration is located in exon 7 (coding exon 7) of the EPHX3 gene. This alteration results from a G to T substitution at nucleotide position 967, causing the valine (V) at amino acid position 323 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
