The c.50A>G (p.Y17C) alteration is located in exon 2 (coding exon 1) of the EPN3 gene. This alteration results from a A to G substitution at nucleotide position 50, causing the tyrosine (Y) at amino acid position 17 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
