Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.649C>T (p.R217C) alteration is located in exon 5 (coding exon 5) of the EPHX3 gene. This alteration results from a C to T substitution at nucleotide position 649, causing the arginine (R) at amino acid position 217 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
