Ambry Genetics

May 21, 2024

The c.850C>T (p.L284F) alteration is located in exon 6 (coding exon 6) of the EPHX3 gene. This alteration results from a C to T substitution at nucleotide position 850, causing the leucine (L) at amino acid position 284 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
