The c.301T>C (p.Y101H) alteration is located in exon 2 (coding exon 1) of the EPN3 gene. This alteration results from a T to C substitution at nucleotide position 301, causing the tyrosine (Y) at amino acid position 101 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
