Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.73C>T (p.R25C) alteration is located in exon 2 (coding exon 1) of the EPN3 gene. This alteration results from a C to T substitution at nucleotide position 73, causing the arginine (R) at amino acid position 25 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
